>>fb-MSZHTH0X thanks for all your hard work

>>fb-T3UI8FSR I appreciate the praise. However, it feels as if these 15+ years of effort haven't really yielded much, if any, positive change.

Good.

>>fb-6NGS9ZK7 Not really, but everyone's entitled to their own opinions.

>>fb-UZQWFM76 (OP) >the possibility or actual result of serious injury That shouldn't invalidate consent. Otherwise extreme sports and pregnancy would be outlawed.

>>fb-PB0QAFRG > That shouldn't invalidate consent. You are welcome to your own opinion. > Otherwise extreme sports and pregnancy would be outlawed. 1. Some regions have laws specifically exempting a sport for a "reasonably foreseeable" hazard (see the first quote below). 2. Pregnancy? This is about factors that invalidate sexual/erotic consent from a legal perspective: "consent" in this case implies both 1) involvement of more than one person, and 2) one person doing something to one or more others. "Consent is a defense to only a few crimes. In most jurisdictions, consent can operate only as a defense to sexual conduct, injury that occurs during a sporting event, and crimes that do not result in serious bodily injury or death (Me. Rev. Stat. Ann., 2010). As the Model Penal Code states, “[w]hen conduct is charged to constitute an offense because it causes or threatens bodily harm, consent to such conduct or to the infliction of such harm is a defense if: (a) the bodily harm consented to or threatened by the conduct consented to is not serious; or (b) the conduct and the harm are reasonably foreseeable hazards of joint participation in a lawful athletic contest or competitive sport” (Model Penal Code § 2.11(2))." https://open.lib.umn.edu/criminallaw/chapter/5-5-consent/ "Certain BDSM sexual practices can be and sometimes are prosecuted under state criminal laws dealing with assault, aggravated assault, sexual assault or sexual abuse. This is true even when there is clear consent. Criminal prosecution can arise in various circumstances, including situations in which one participant is injured requiring medical treatment and the injury is brought to the attention of the police by hospital staff, doctors or a family member." ... "Technically speaking, any type of “impact play” is illegal. One person cannot legally give their consent to being physically assaulted. As far as the law and courts are concerned the issue becomes one of violence, not sex. The criminal offense is that one person is causing another person physical harm. To contrast, the issue of consent is different for BDSM cases than it is for a rape case, for example." "In a rape case, the sex act is not considered criminal unless it can be shown that one party did not consent. In a BDSM case, however, the causing of physical harm is in and of itself criminal. The question then becomes the extent to which the courts will allow such criminal conduct to be excused by one person’s consent." https://pridelegal.com/assault-consent-bdsm-law/

>>fb-TQUX9B8M > Pregnancy? This is about factors that invalidate sexual/erotic consent from a legal perspective: "consent" in this case implies both 1) involvement of more than one person, and 2) one person doing something to one or more others. That is, in the context of immediately causing, or posing a threat of causing, serious injury to another person. Pregnancy isn't quite comparable, and it's a red herring besides (same with sports).

@anorectal violence anon you should post on 3ch.one i think they'd be interested in your mission

>>fb-K8KG639Z Hmm. I saw a similar invitation on another chan to a different chan. I appreciate the invitation, but I'll decline it for now. That may change if this new 3ch turns out to be neither yet another short-lived Patchchan nor a pedochan.

>>fb-B52QZOSE I brought it up because there are some people who want to abolish pregnancy because it is harmful to women. See https://spinster.xyz/@AbolishPregnancy >>fb-TQUX9B8M The only way I could tell you were referring to the USA was that the TLD for your reference link was ".edu". But anyway, that's interesting about the legality of it. I don't think I agree with you on the ethics of consent but I don't really want to defend BDSM so I think I'll leave it. Also, legality ≠ ethics.

>>fb-Q9GYVZ8I > I brought it up because there are some people who want to abolish pregnancy because it is harmful to women. It _can be_ harmful to women to varying degrees, but it currently is necessary to continue the species until we have some other practical means. Regardless, both pregnancy and any effort(s) to abolish it are irrelevant (i.e., they are red herrings). I wrote about several logical fallacies in the last paste included in the OP image covering logically-fallacious diversionary tactics: a red herring is one of them. https://iep.utm.edu/fallacy/#RedHerring > The only way I could tell you were referring to the USA Misrepresentation (i.e., putting words into someone's mouth) is also covered in the paste mentioned above. I quoted two sources covering U.S. laws; doing so neither means nor implies that such legal concepts are limited to states in the U.S. The issues covered most certainly are not limited to the U.S. alone. I wrote this in the OP image: "Due to its ubiquity in pornography, several generations now have grown up masturbating to, demanding more of, and seeking to emulate violent behavior that should easily be considered severely criminal when more than one person is involved." I call that the "decadence" paste, and it recently was revised to make it less opinionated, e.g. by changing "should easily be considered severely criminal when more than one person is involved" to "arguably should easily be considered severely criminal when more than one person is involved (at the very least for potentially-lethal outcomes/sequelae)." No specific region was mentioned, and it could be argued that such legal concepts should be applicable worldwide. Fatality most certainly is a potential consequence for a person on the receiving end of anorectal violence as defined (anoreceptive activity involving a combination of rapid thrusting, considerable girth, and a prolonged duration): "We describe a case of a 45-year-old white woman who sustained devastating homicidal colorectal trauma that served as a primary cause of death in the setting of rape. Our patient sustained a 15-cm laceration of the anterior rectal wall and ultimately died of peritonitis and sepsis. Death from rectal perforation and sepsis in the setting of sexual assault is rare and has only been documented in 3 other cases, 2 pediatric patients and 1 elderly debilitated patient. Other representative and unique methods of perforation are reviewed along with a brief discussion of the development of peritonitis after perforating colorectal trauma." "Fatal anorectal trauma in the setting of sexual assault: case report and literature survey." The American Journal of Forensic Medicine and Pathology. 2010 Sep; 31(3): 273-7. PMID 20512029. doi:10.1097/paf.0b013e3181e13269.

>>fb-ILH7W4ZS Oops, I meant to post that with Trends & Associations.

NSFW Content

>>fb-Q9GYVZ8I > legality ≠ ethics No such suggestion was made. Rather, it is being argued that anorectal violence as defined should have criminal implications when more than one person is involved. That is due not only to direct consequences of inflicted trauma, but also indirect consequences: e.g. medical treatments (especially surgery) for anorectal conditions can have a variety of unpleasant and even dangerous outcomes, and so anorectal violence very well could lead to a receptive person's quality of life diminishing suddenly and severely. >>fb-ILH7W4ZS > it could be argued that such legal concepts should be applicable worldwide. Aside from relevant sources quoted in Trends & Associations (such as the Australian abc.net.au article), there also is this: https://www.theguardian.com/society/2022/aug/11/rise-in-popularity-of-anal-sex-has-led-to-health-problems-for-women

>>fb-8CRL1PYE >reddit bullshit & omission [rb&o] Common themes include: • Advice to go slow _at first_ • Advice to stop if there is any pain Details: There are very fragile and pain-insensate tissues not far inside (refs: AR1-3 and A&T). • Advice to try "anal training" (stretching) with insertions of progressively increasing circumference Details: Anal stretching is likely to damage one or both anal sphincter muscles (refs: AR1-3 and especially P&I). • No one mentioning the possibility of one or more preexisting anorectal conditions Details: Such conditions may be quite common (although perhaps frequently going undiagnosed/unreported), may be asymptomatic in some cases, and also can arise e.g. as a consequence of anorectal surgery, pregnancy, and defecation trauma. Erotic anorectal trauma is a completely avoidable causative factor (as is surgical trauma when it's due to treatment for one or more consequences of erotic anorectal trauma). Furthermore, in some cases there is an admission (or at least strong implication) of significant erotic anorectal trauma in the past. All of this brings me to my next point... • No one saying something like "doing that is a bad idea" (probably relating to /r/sex's enshrinement of the sex-positive bias) In future posts I shall cover relevant issues found in specific archived URLs included in rb&o.

>>fb-494LLMUL > Erotic anorectal trauma is a completely avoidable causative factor Voluntary, that is.

>>fb-494LLMUL > In future posts I shall cover relevant issues found in specific archived URLs included in rb&o. Alright, to start off I'll say this: My comments on specific archive snapshots of Reddit /r/sex threads should be considered works-in-progress, and some could eventually be included as part of rb&o. I am a revisionist writer, and so changes probably will be made over time. Constructive criticism is welcome, and it may be used to improve my commentary. Also, it can be quite difficult to hold myself back sometimes; remaining neutral and non-opinionated is difficult when confronted with a flood of material from others that is one or more of lacking, misleading, false, ignorant, dangerous, malicious, and insane (by every definition of the word). One more thing to note is that "anal sex," a far-too-common term, is one I avoid using myself due to it being both vague (generally it refers to anal intercourse, but not always: some people use the term to refer to other/additional anoreceptive activities) and a likely misnomer: anal eroticism has nothing to do with sexual reproduction (well, barring strange and unusual occurrences that is, e.g. impregnation via sperm migrating to the vagina through a rectovaginal fistula).

https://web.archive.org/web/201706/https://www.reddit.com/r/sex/comments/5vod72/anal_skin_tag_so_i_have_an_issue_that_embarrasses/ OP says she has an anal skin tag, and is concerned about its appearance. 1) One or more anal skin tags can be indicative of anal stenosis and/or other preexisting conditions. 2) There are other possibilities for what a perianal lump may actually be. 3) Anoreceptive activities can make things worse and instigate development of additional issues, including more lumps (anal skin tag, prolapsed internal hemorrhoid, etc). Note: The top commenter with the most points is a moderator of /r/sex, alittlebirdy1. I've seen him repeatedly spread health-harmful falsehoods many times over the years: It probably is disinformation (intentional / due to malice, e.g. psychopathy) rather than misinformation (accidental / due to ignorance). https://web.archive.org/web/201706/https://www.reddit.com/r/sex/comments/5tqtzt/did_i_ruin_my_life_by_having_anal_sex/ OP says she had casual "sex" involving only anal and oral eroticism. It certainly is reasonable for any future partner to find that significantly concerning. Furthermore, the top commenter wrote that "Sex is a positive thing, not negative, and your sexual preferences are a small part of who you are." Erotic activities most certainly can be negative, and also they _and their consequences_ can impact a person's life considerably in very significant ways. https://web.archive.org/web/201706/https://www.reddit.com/r/sex/comments/4p3qr4/anal_sex_what_are_the_risks_of_unprotected_anal/ 1) Nobody pointed out the traumatic risks. 2) Several commenters claimed that they engage in regular anal activities with neither partner experiencing any health issues: That is highly improbable if those activities ever involved one or more of a lubricant that irritates/damages the rectal lining, rapid thrusting, inserting anything significantly girthy, and a prolonged duration. Furthermore, one instance of trauma is sufficient for development of one or more preexisting conditions that could render further anoreceptive activities even more damaging. https://web.archive.org/web/201706/https://www.reddit.com/r/sex/comments/45dnm4/question_i_f_am_really_scared_of_anal_sex_and/ Top comment: "in general, anal sex by itself causes no permanent changes to the anus." Not only can anal eroticism result in permanent changes to a person's anus (and rectum), some of which may be visible externally, but also such changes probably are quite common nowadays owing to rampant ignorance, misinformation, and disinformation about anorectal topics along with mainstream pornography setting a very bad (arguably blatantly criminal) example that far too many people [wish/try to] copy. https://web.archive.org/web/201706/https://www.reddit.com/r/sex/comments/3uw0i1/question_my_girlfriend_loves_rough_anal_sex_is_it/ 1) No one pointed out that rapid thrusting is _always_ a bad idea at least in the context of anal intercourse and object insertions. 2) The top commentor with many upvotes wrote "If there is any pain or sign of bleeding stop." Another commenter with many upvotes wrote "You are only supposed to go slow in the beginning." Significant damage can occur to a receptive person's anorectum with no pain whatsoever. In fact, such damage is _likely_ to occur with rapid thrusting (again in the same context), especially combined with one or more of a girthy penis/object, a prolonged duration, and repetition of the activity over time.

https://web.archive.org/web/201706/https://www.reddit.com/r/sex/comments/6f83ve/anal_buttsex_shit_for_hours_nausea/ Here's what the OP wrote: "I'm (29F) struggling with the after effects of buttsex with (35M).He's got a lot of cock and we're really rough, and that's cool. Usually sex is less like "sex" and more like I'm just holding on trying to not die. It's fun." The top commenter suggested "try slightly more gentle anal." Nobody suggested refraining from further anoreceptive activities entirely and reporting what should arguably be considered severely criminal behavior. The OP may well be sexually masochistic to a pathologic degree, of course... https://web.archive.org/web/201706/https://www.reddit.com/r/sex/comments/6e1a9b/skin_tag_prevents_anal_sex_any_advice/ The OP wrote "We both really enjoy anal sex (we both enjoy both giving and receiving FWIW). My wife has huge orgasms from anal. But a few years ago she got a skin tag right on her anus. It makes anal sex impossible because as I push in (on the in stroke) it grabs the tag and pulls it, causing a lot of pain." He then went on to say he misses engaging in anal intercourse with his wife, and asks for advice including whether "we [should] just accept that we can't have anal sex anymore." Nobody pointed out that 1) the anal skin tag probably was a result of their activity, and that 2) yes, they should indeed refrain from engaging in any further anal intercourse. https://web.archive.org/web/201705/https://www.reddit.com/r/sex/comments/6dxpmq/embarrassing_questions_about_anal/ The OP wrote "I enjoy anal sex. It's one of my favourite ways to orgasm, especially when it's pretty hard and rough." Did anyone explain that engaging in anal eroticism in a "hard and rough" manner (not to mention spontaneous) is both very risky and a terrible idea? Of course not. This may be another OP with severe sexual masochism disorder. https://web.archive.org/web/201705/https://www.reddit.com/r/sex/comments/6dxh7l/trouble_with_anal_sex/ The OP wrote "Been with my current partner nearly 8 months now and in that time have managed to had successful anal sex about 8 times. Now my boyfriend is really into it but I am just struggling to get comfortable with it. IT HURTS like 80% of time time, to the point where I ask to stop. I want to be better at it for him, as I know he loves it. I have tried trainer kits of looked up all kinds of advice but nothing seems to be working for me..." Nobody pointed out that anal stretching is a bad idea, mentioned the possibility of one or more preexisting conditions, or advised refraining from engaging in anal intercourse entirely. https://web.archive.org/web/201706/https://www.reddit.com/r/sex/comments/5vu4mk/ive_f29_been_having_regular_anal_sex_for_nearly/ "I've [f/29] been having regular [anal] sex for nearly 10 years now. I'm starting to worry about what might be the consequences. Can anyone shed any light on this?" Nobody covered anywhere near the amount of traumatic risks I've covered, and also several posts contain blatant falsehoods. And speaking of alittlebirdy1 spreading falsehoods ... "There are no scientific studies that I'm aware of that show issues with anal sex. [...] The anus is designed to open and close on a regular basis. You're not going to damage it with sex unless you're doing sex wrong."

jesus, wtf is this schizothread

https://web.archive.org/web/202012/https://old.reddit.com/r/sex/comments/6jwcqk/anal_with_a_very_girthy_penis_help/ 1) Nobody suggested not having anal intercourse with someone who has a very girthy penis. 2) The top commenter suggested anal stretching. 3) The OP wrote she had anal intercourse with a previous partner who had a penis with significant girth albeit less than the new one, and yet no one pointed out the possibility of one or more preexisting anorectal conditions arising from trauma caused by that previous partner. https://web.archive.org/web/202012/https://old.reddit.com/r/sex/comments/6itbkm/anatomy_question_anal/ The OP wrote "I'm quite a large joe;" he seemed to be referring to length alone. Nobody pointed out that the anorectum's lining above the pectinate line lacks somatic innervation, i.e. significant damage can occur with no pain whatsoever. One commenter with many upvotes even claimed that "There's a lot of sensitive nerves in there, even up at the sigmoid colon..." While there may well be many nerves along the rectum and even the sigmoid colon, the innervation they provide probably is _visceral_ rather than somatic at least at the epithelial layer (if there are any intraepithelial nerve fibers: there may not be), meaning there won't be any somatic pain when at least epithelial damage is occurring. [I may revisit this at some future point after further researching related topics, including sigmoid innervation and sigmoid perforation.] https://web.archive.org/web/201706/https://www.reddit.com/r/sex/comments/6fjrrt/rough_anal_aftercare_fisting_questions_lube/ The OP wrote "The guy that I am seeing really enjoys rough anal- which can be, and is, incredibly satisfying- but also painful at times." Nobody suggested discontinuing any further anoreceptive activities, the possibility of one or more conditions being present as a result of such behavior, or potential criminality. One commenter even suggested anal stretching, and nobody pointed out that anal fisting (mentioned by the OP) is a terrible idea. https://web.archive.org/web/201706/https://www.reddit.com/r/sex/comments/6fjfj9/anal_wifes_butthole/ The OP wrote "We enjoy some anal fun from time to time. Which is awesome that I found a woman who is into that (its like my only kink). Thing is her butthole doesn't look normal and its kinda a turnoff. There are 3 large skin tags/hemorrhoids/something that basically make up the outside..." Nobody pointed out that those issues quite possibly were caused by their activities, nor did anyone suggest discontinuing such activities. In fact, the top commenter wrote "Just how she is. [...] DO NOT TELL HER" https://web.archive.org/web/201706/https://www.reddit.com/r/sex/comments/6famab/i_m_am_very_much_into_the_idea_of_pretty/ OP's thread title: "I [M] am very much into the idea of pretty heavy/intense [anal training & stretching], but I'm afraid I'll never meet a woman who likes it in the same way..." Did anyone point out that anal stretching is a bad idea? Of course not.

https://web.archive.org/web/202004/https://old.reddit.com/r/sex/comments/g30qux/daily_anal_ok/ The OP is asking whether daily "anal" (presumably anal intercourse) is okay. The OP is also concerned "about the water based lube having some kind of drying effect on the rectum or sphincter muscles." No one mentioned traumatic risks beyond fecal incontinence. That includes the potential for some lubricants to irritate or damage the rectal lining. https://web.archive.org/web/202004/https://old.reddit.com/r/sex/comments/g1dyh1/bf_wants_to_do_anal/ The top commenter suggests _starting_ slow: rapid thrusting is _always_ a bad idea. https://web.archive.org/web/202004/https://old.reddit.com/r/sex/comments/g02vby/is_anal_good_for_your_health/ The top commenter suggests that anal eroticism could be good for a receptive person's health "if it turns you on and improves your overall sex life." I shouldn't even need to comment on that one. Furthermore, another commenter suggests anal stretching. https://web.archive.org/web/201907/https://old.reddit.com/r/sex/comments/c7k11p/first_time_anal_sos/ The top commenter with many upvotes wrote: "My ass [probably referring to the anorectum] is back to normal less than an hour after the roughest anal with bf and he's not exactly a small man." It's unclear how that person defines "normal," but no one pointed out that "rough anal," which usually refers to rapid thrusting and certainly refers to anal intercourse in this case, is a very bad idea. https://web.archive.org/web/201707/https://www.reddit.com/r/sex/comments/6kj7qw/what_does_anal_sex_feel_like_for_women/ The top commenter with many upvotes wrote: "I take deep breaths and exhale while he pushes himself inside of me. We slowly do this until his entire penis is inside of my ass (8 inches is a lot to take up the ass). Once it's all the way in, and can easily slide in and out, we get rough. Like, slam into me rough." Did anyone point out the risks of doing so or mention potential criminality? Of course not. That poster may well have a severe case of sexual masochism disorder. It could also/instead be a malicious narrative intended to promote harmful behavior.

https://web.archive.org/web/202006/https://old.reddit.com/r/sex/comments/gxg3ec/i_can_only_enjoy_anal_when_it_hurts/ The OP wrote "I [23/F] have always enjoyed pain during anal intercourse... I am really concerned. Why am I so messed up? Why do I enjoy this?" Nobody mentioned sexual masochism disorder. Several commenters suggested that the OP is fine. https://web.archive.org/web/202004/https://old.reddit.com/r/sex/comments/g6e6gc/super_weird_questioncan_lots_of_anal_weakenloosen/ The OP asks: "Can lots of anal weaken/loosen vaginal muscles?" The top commenter wrote "No. Nor does it weaken anal/rectal muscles." Anoreceptive activities _can_ cause permanent damage to, and consequently weaken, one or both anal sphincter muscles at the least (there are other muscles in the region such as those of the pelvic floor). https://web.archive.org/web/202004/https://old.reddit.com/r/sex/comments/g4hqw8/what_happens_after_anal/ The OP wrote "I’ve (20f) been wondering what happens after anal? Kind of like repercussions or short/long term effects?" There are many problems here: 1) Several commenters suggested that there will be no health consequences. 2) The top commenter wrote "I’ve had a lot of anal, both rough and gentle. I haven’t had any health repercussions, at least not yet." 3) The second commenter wrote "anal sex should be completely safe." 4) Another commenter wrote "It's completely safe if you follow the advice, start slow. If it hurts, stop immediately." https://web.archive.org/web/202004/https://old.reddit.com/r/sex/comments/g43bnx/anything_put_in_my_ass_hurts/ The OP wrote "A couple times we've tried anal I have been able to wait until he cums, but the two other times I have not been able to bear the pain, and asked him to stop. Either way, the whole time I am in extreme pain..." Nobody pointed out the possibility of one or more preexisting anorectal conditions. One commenter wrote "You can end up hurting yourself and damaging your rectum, so please stop if it hurts." Nobody pointed out that significant damage can occur with no pain whatsoever. https://web.archive.org/web/202004/https://old.reddit.com/r/sex/comments/g35tb5/gf_and_me_are_trying_to_get_into_anal_sex_but_we/ The OP wrote in the thread title: "Gf and me are trying to get into anal sex but we are both new to it." The top commenter advised: "Start extremely slow and small." 1) Anal stretching is a bad idea, so telling someone to _start_ small is terrible advice. 2) There are quite delicate tissues not far inside that can be damaged without pain, so advising someone to _start_ slow also is terrible advice.

If this place truly is shutting down permanently soon, then I'll miss it.

For far too many years now the subreddits mentioned above have been encouraging, glorifying, and inciting anorectal violence in particular that arguably should easily constitute severely criminal behavior when more than one person is involved (at the very least for potentially-lethal outcomes/sequelae). Perhaps people at high levels of Reddit should be held accountable: not only for failing to uphold their own site's policies, but also for enabling the spread of very dangerous violent behavior along with health-harmful falsehoods and omissions facilitating it on subreddits such as /r/sex.

>This place is still going. Great! In the spirit of continuing against all odds, I shall resume as well. I've already completed [preliminary/WIP] commentary on more than what I've posted here (this post included). I'll still take my time, however: Doing so gives me a chance to review what I've already written at a later point and make any changes that come to mind. Bear in mind that they remain subject to change, and that useful feedback is very welcome. https://web.archive.org/web/202006/https://old.reddit.com/r/sex/comments/h13li6/once_you_go_too_big_on_anal_can_you_still_hold_it/ The OP's thread title: "Once you go too big on anal can you still hold it in?" The most-upvoted commenter, alittlebirdy1, wrote: "Yes. This is old fashioned homophobia, nothing more. A sphincter is designed to open and close, else you're lose the ability to hold in your shit after too many large turds. [...] Unless you tear things (repeatedly), anal doesn't impact incontinence." Anal stretching can easily damage one or both anal sphincter muscles at the least. Damage to >= 2 muscles of the anal sphincter complex (internal anal sphincter, external anal sphincter, and puborectalis) is strongly linked to fecal incontinence. https://web.archive.org/web/202006/https://old.reddit.com/r/sex/comments/h13f4l/is_anal_safe/ The OP wrote "My bf wanted to do anal for a long time and he has put his finger in and I like it but it hurts and it’s stresses me out. I know the more we do it that the pain will go away but what about the after math.? If heard that some people can’t control their poop and I don’t want that. And I think you can get like infection more easily..." 1) No one pointed out the possibility of one or more preexisting conditions, nor did anyone suggest refraining from anoreceptive activities entirely and perhaps consulting a medical doctor. 2) One commenter, alittlebirdy1, quoted what OP claimed to have heard that "some people can’t control their poop" and wrote this in response: "That's nonsense." Fecal incontinence most certainly is a potential consequence of anoreceptive activities. alittlebirdy1 then continued: "The only way you'll cause incontinence issues is through tearing the muscle there - typically, repeatedly, as the human body has great ability to heal." Fecal incontinence can arise as a consequence not only of muscle damage, but also of hemorrhoidal disease, a fistula, etc. Several other commenters advised to go slow _at first_.

https://web.archive.org/web/202006/https://old.reddit.com/r/sex/comments/hcxxec/wanting_to_incorporate_anal_in_my_regular_sex/ The top commenter wrote "Porn actresses do all those routines because you see a 20 minute video, but they film and refilm for hours. So they dont just mentally prepare, they use large toys to stretch and tire out the anal sphincter, to do 4 hour shoots and so they can gape and other destructive behaviors (gaping does not occur in normal anal sex)..." 1) Stretching doesn't "tire out" the internal anal sphincter so much as cause permanent damage to it at least for any receptive person for whom it wasn't already damaged. 2) Gaping is not destructive behavior: rather, it can be a consequence of destructive behavior. https://web.archive.org/web/202006/https://old.reddit.com/r/sex/comments/hc8o9m/virgin_anal_and_wondering_what_to_expect/ The top commenter suggested "taking it super slow to start with." Rapid thrusting is never a good idea. https://web.archive.org/web/202006/https://old.reddit.com/r/sex/comments/ha2b43/is_there_such_a_thing_as_too_much_anal/ The OP's thread title: "Is there such a thing as too much anal?" The OP went on to claim: "GF (45f) and I (44m) have frequent anal sex. 4-5 times a week, sometimes multiple times a day. [...] It's been this way pretty much our entire 1.5 years together. She doesn't seem to have any adverse effects, but I just can't help but wonder if there's any potential harm that's being done unintentionally. [...] *edit to add that we always make sure to use plenty of lube. The last thing in the world that I would want is to hurt her." It's possible that the OP is exaggerating, or even flat out lying. 2) Nobody pointed out that it is very easy to cause physical harm to a receptive person's anorectum unintentionally. The OP later claimed: "Yeah, [there is] no prolapse. Occasionally she wants to have me gape her for pics or video and we've even worked our way up to almost my whole hand..." Nobody pointed out that anal stretching is a bad idea either. RubyRyder, a pornstar I've seen numerous times over the years spreading what is quite likely to be disinformation, made two comments with health-harmful falsehoods. First comment: "I even teach a webinar about advanced anal play with wider and longer toys, how to do it safely." Anal stretching is not safe for anyone with intact anal sphincter complex muscles, nor is insertion of lengthy objects: 1) the internal anal sphincter muscle can be damaged without pain, and 2) colorectal perforation can occur without immediate pain. Another RubyRyder comment: "Anal sex most decidedly does not cause hemorrhoids, in fact the massaging effect of anal sex in the rectal canal brings more blood to the area and helps avoid them, and even treat ones that are not external (prolapsed)." Anoreceptive activities most certainly can cause damage both a) leading to development of hemorrhoidal disease, particularly prolapse of the internal hemorrhoidal cushions resulting from frictional sliding force on them and/or their supporting tissues — both of which lack somatic innervation (i.e., they can be damaged without pain), and b) worsening existing hemorrhoidal disease.

https://web.archive.org/web/202010/https://old.reddit.com/r/sex/comments/jiofki/how_do_i_20f_enjoy_anal/ The OP wrote: "I’ve been been hooking up with a guy (22M) who asked me to try anal. A while ago we tried it. I was on all fours and he started putting his dick in. There was no lube and he kinda shoved it in quickly. I immediately felt a ton of pain. [...] I’m a pretty small person and when I lost my virginity it hurt a lot at first. Even now, I always feel pain at first when he puts his dick in. But the pain is 10x worse in my ass and it just continues to hurt. Idk how to make it more enjoyable for me." Nobody suggested seeing a medical doctor, mentioned the possibility of one or more preexisting anorectal conditions being present, or advised against engaging in any further anoreceptive activities. https://web.archive.org/web/20200713030150/https://old.reddit.com/r/sex/comments/hphlnl/asap_help_rough_anal_everything_hurts/ [The original post was deleted in later snapshots, so a specific older one is referenced.] The OP wrote: "I (23f) had some very under the influence rough sex with my partner, not just vaginally but anally, and now it absolutely hurts to a whole new level when I need to use the bathroom & I constantly need to use #2 and that hurts the most..." 1) Nobody mentioned that rough anal intercourse is always a bad idea. 2) No one pointed out potential criminal implications. 3) Nobody suggested going to a hospital, or at least seeing a medical doctor ASAP. https://web.archive.org/web/202007/https://old.reddit.com/r/sex/comments/hon4kd/tips_for_trying_anal_again_with_my_husband/ The OP wrote in the thread title "Tips for trying anal again with my husband" then went on to write "before we had kids I was into getting rimmed or him putting a finger in while we fucked and stuff like that. I let him try to put his cock in a couple times but it fucking hurt. [...] So, I'm wondering if anyone who tried it a couple times and found it very painful were able to turn it around and actually enjoy it?" 1) Nobody mentioned the possibility of one or more preexisting anorectal conditions, especially such conditions arising in connection with pregnancy and obstetric trauma. 2) The top commenter wrote "you need to go very very slowly initially. [...] There shouldn’t be any pain, so don’t ignore it if there is." Rapid thrusting is always a bad idea, and significant damage can occur with no pain. 3) Several commenters suggested anal stretching, which is not a good idea. https://web.archive.org/web/202006/https://old.reddit.com/r/sex/comments/hetvgj/is_anal_every_night_bad_for_you/ The OP asked: "I really, really, REALLY, like to do anal. Is it bad if I do it every single night?" The OP did not define what was meant by "anal." 1) The top commenter claimed: "I have had something up my ass every day for the last 10 years. I have a large collection of very large toys and my asshole is still the tightest around." That is very likely to be blatant bullshit: anal stretching with "very large toys" alone would've caused permanent damage to one or both anal sphincter muscles at the least. Barring anatomic anal stenosis (i.e., the presence of constricting scar tissue), it would be highly unlikely for the person's anus to be "the tightest around" after engaging in such activities — especially repeatedly. 2) Another commenter with many upvotes suggested anal training/stretching. That same person also wrote "if it hurts slow down:" significant damage can occur with no pain.

https://web.archive.org/web/202109/https://old.reddit.com/r/sex/comments/kgmu04/i_used_to_love_anal_and_now_my_anatomy_is/ The original post was deleted; normally I try to avoid referencing snapshots for which that is the case. Anyway, the top commenter wrote: "When my wife and I were first dating, she told me she liked anal sex, before we'd even done it. [...] We had anal once in a while, maybe once every few months... And then, she [developed diseased] hemorrhoids. Not because of having anal as far as I know, just because." Their activities may well have been responsible. Another commenter suggested anal stretching. RubyRyder wrote: "Plugs should not give you a hemorrhoid. Hemorrhoids are caused by a lack of blood flow in the area (read tension) and straining. Ways to calm down hemorrhoids are doing Kegels and rectal canal massage, which brings more blood flow to the area." Frictional sliding in the anal canal can painlessly damage the internal hemorrhoidal cushions and/or their supporting tissues, either worsening existing internal hemorrhoidal prolapse or instigating its development. https://web.archive.org/web/202012/https://old.reddit.com/r/sex/comments/kf6ryw/anus_rectum_transformation/ The OP wrote: "My gf(26) loves anal sex but we don’t do it very often because she is afraid her anus/rectum gets different." The top commenter, alittlebirdy1, wrote: "Does your asshole get ruined by pooping? No? Why would sex do anything different?" Anoreceptive activities can be, and often are, rather more intense than defecation. Fecal matter travels only one way, should be soft for healthy people with a decent diet, and defecation is a relatively brief process. By contrast, some all-too-common anoreceptive activities involve vigorously thrusting a firm, girthy, and possibly lengthy object or body part in and out for a prolonged period of time. https://web.archive.org/web/202011/https://old.reddit.com/r/sex/comments/jm8otr/i_really_want_my_girlfriend_to_peg_my_ass_is_it/ The OP's thread title: "I really want my girlfriend to peg my ass. Is it safe. Im scared of getting fistulas and anal prolapse." One commenter claimed "im a male who has been into putting things inside my own ass for 55 years. Very large things for about the last 35 of those. I have been fisted many times with large hands, a few times to the elbow. I have never had issues with fistulas, or incontinence. I don't prolapse at all." The person could well have been exaggerating or outright lying. Regardless: 1) Anal stretching, especially done repeatedly, is likely to cause permanent muscle damage leading to fecal incontinence. 2) Internal hemorrhoidal prolapse at least is a likely consequence of repeated and vigorous thrusting (i.e., frictional sliding) with a girthy object or body part. https://web.archive.org/web/202010/https://old.reddit.com/r/sex/comments/jip6lw/what_are_the_long_term_effects_of_anal/ The OP wrote: "I(20F) just started doing anal with my SO(23M). We both love it, but I have recently started to think of the effect it may have on my asshole overtime..." 1) Nobody mentioned traumatic risks beyond anal fissures. 2) One commenter wrote "Anus is basically sphincter muscle. Just like every other muscle it can be stretched without losing control over it. Problem is when that muscle isn't strong enough. That's why PC muscle excercises exist." Anal stretching is likely to cause permanent damage to one or both anal sphincter muscles. Furthermore, the internal anal sphincter is an involuntary muscle, so exercises do not strengthen it. 3) Another commenter claimed: "It depends on how regularly you do anal but so long as you aren't trying to or taking stupidly big stuff up there, you'll have little to no long term effects from doing anal if you prepare right." Not only can significant damage occur from one instance of trauma, but also preparation will not prevent damage from occurring e.g. when thrusting is too rapid or when something too girthy is inserted.

>>fb-BMVUTY56 Here's another study covering visceral pain: "Visceral pain has five important clinical characteristics: (1) it is not evoked from all viscera (organs such as liver, kidney, most solid viscera, and lung parenchyma are not sensitive to pain); (2) it is not always linked to visceral injury (cutting the intestine causes no pain and is an example of visceral injury with no attendant pain, whereas stretching the bladder is painful and is an example of pain with no injury); (3) it is diffuse and poorly localised; (4) it is referred to other locations; and (5) it is accompanied with motor and autonomic reflexes, such as the nausea, vomiting, and lower-back muscle tension that occurs in renal colic (panel).1 The mechanisms responsible for these clinical features of visceral pain have been reviewed previously. 1, 2" "The fact that visceral pain cannot be evoked from all viscera and that it is not always linked to visceral injury has led to the notion that some viscera lack afferent innervation. We now know, however, that these features are due to the functional properties of the peripheral receptors of the nerves that innervate certain visceral organs and to the fact that many viscera are innervated by receptors that do not evoke conscious perception and, thus, are not sensory receptors in the strict sense. Visceral pain tends to be diffuse because of the organisation of visceral nociceptive pathways in the central nervous system, particularly the absence of a separate visceral sensory pathway and the low proportion of visceral afferent nerve fibres, compared with those of somatic origin (figure 1). 3 The nausea and diaphoresis that accompanies angina is an example of autonomic responses provoked by visceral pain that serve as a warning to the individual to “slow down”." "Visceral pain." The Lancet. 1999 Jun 19; 353(9170): 2145-8. doi:10.1016/S0140-6736(99)01306-9. (PMID 10382712) >>fb-MDPV86CZ > colorectal perforation can occur without immediate pain. Some references for that: "Colonic perforations may present without immediate perforation-associated pain and tend to have a slower clinical progression, with the development of a secondary bacterial peritonitis or localized abscess formation [16,17] partly due to the relatively neutral and nonerosive nature of the chemical environment within the colon [12]. With some exceptions, peritoneal contamination from intraluminal colonic contents progressively leads to purulent or fecal peritonitis or to the development of an intra-abdominal abscess. Few of the more than 500 different microfloral species in the colon can survive outside their normal environment [12,18]. In fact, only 22 genera of bacteria were isolated from cultures of intra-abdominal fluid collected among 255 patients who had secondary bacterial peritonitis [5,19]. Over 70% of isolates were from the genera Bacteroides, Streptococcus, Escherichia, Peptostreptococcus, and Fusobacterium [5,18,19]." "Gastrointestinal perforation and the acute abdomen."

Clinical presentation varies: oesophageal perforations can present with non-specific symptoms such as acute chest pain, odynophagia and vomiting [2], gastroduodenal perforations typically present with acute abdominal pain [1, 3], whereas colonic perforations tend to follow a slower progression course, presenting with secondary bacterial peritonitis or localised abscess formation [1, 4].

https://web.archive.org/web/202012/https://old.reddit.com/r/sex/comments/kkc42u/which_hand_is_easier_to_use_for_self_anal_fisting/ Nobody pointed out that anal stretching, inclusive of anal fisting, is a bad idea. https://web.archive.org/web/202012/https://old.reddit.com/r/sex/comments/kjt47n/f26_i_dont_like_sexualising_my_butthole/ OP's thread title: "F26, I dont like sexualising my butthole." She went on to write (reformatted): "I am so uncomfortable with the recent appreciation of buttholes as a sexual part of the body. Don't get my wrong, I'm not against anal sex and will happily eat ass, but I'm so uncomfortable with my own butthole. For one, I've got haemorrhoids, which is whatever, a me-problem, and so the thought of someone seeking to look at my butthole for visual arousal makes me cringe." The OP seems to be confusing two very different, often mutually-exclusive attractions: the aesthetics of the anus and sticking things into one. The former seems to be quite uncommon compared to the latter, and yet the OP made this claim later in the thread: "there definitely has been a recent trend in the appreciation of butts and buttholes." Far too many people seem not to care about another person's anus even if that other person is a significant other. Were that not the case, then rampant, anus-mutilating anorectal violence would have strong opposition; instead, there is an absence of such opposition and has been for many years now. https://web.archive.org/web/202012/https://old.reddit.com/r/sex/comments/kja9a0/why_isnt_anal_working/ OP's thread title: "Why isn’t anal working?" OP goes on to write: "I’ve searched it up, we’ve tried so many times. We’ve talked about wanting to try anal and she’s totally down for the idea. We use a LOT of lube, we make sure we’re both really into it and have been going at it for a while before we even think to try it, we’ve tried different positions. I’ve let her get on top so that she could control the speed but it just doesn’t go in, and she’s in pain before my head is in all the way." 1) Nobody mentioned the possibility of one or more preexisting anorectal conditions. 2) Several commenters suggested anal stretching. https://web.archive.org/web/202205/https://old.reddit.com/r/sex/comments/khcovl/how_big_is_too_big_anally/ The OP asks: "How big is too big [girthwise] anally?" One commenter claimed: "The human anus can stretch 7 inches without getting permanent damage." Another commenter claimed: "Technically a fist could go in there without damaging sphincter function." For any receptive person who has intact muscles of the anal sphincter complex, the first claim is dangerously false (internal anal sphincter damage/rupture has been reported after insertion of a 40mm/4cm-wide rectoscope during transanal endoscopic microsurgery; wider insertions are very likely to cause permanent muscle damage for anyone whose muscles weren't already damaged — gradually increasing circumference of insertions as in "anal training" probably will cause cumulative muscle damage) and so too may be the second (although fist sizes can vary, and some may insert fingers before making a fist). There are many studies pointing out that anal dilatation/stretching is likely to permanently damage one or both anal sphincter muscles at the least. That's because it used to be an accepted treatment for anal fissure, but has fallen out of favor due to unacceptably high rates of fecal incontinence owing to muscular damage demonstrated by anal endosonography.

"Previous studies (Speakman [25], McDonald [26] and Van Tets [27]) have reported alterations in the sphincter apparatus after anal dilatation or after the use of anal retractors to treat anorectal pathology. These studies demonstrated morphological alterations in the sphincters, but did not assess sphincter function. The results of those studies — indicating the danger of permanent injury to the sphincter and the underlying risk of incontinence — argued against the use of anal dilatation in the treatment of anorectal pathology. However, TEM [Transanal Endoscopic Microsurgery] differs from the techniques assessed in these studies because it requires a sustained, controlled anal dilatation rather than manual dilatation or the expansion caused by anal retractors. This may explain the difference in the results obtained by our group [17,28] and other studies of the same topic." "Our study was designed to obtain manometric and clinical data in patients undergoing TEM in the preoperative period and from at four months after the intervention. Most studies have followed patients for at most six months, except the study by Allaix et al. [29] which followed 93 patients for five years. It is generally agreed that TEM causes BP [baseline pressure] and VCP [Voluntary Contraction Pressure] to fall in the postoperative period, though the values tends towards normalization around four months postsurgery. No studies have detected any permanent alterations beyond a year after surgery. TEM appears to cause alterations in both smooth and striated muscle; whereas the striated muscle recovers in the postoperative period the smooth muscle does not. However, the Wexner scores results show that these changes do not lead to clinical incontinence." "Study of anorectal function after transanal endoscopic surgery."

A condom or protective barrier should always be used for anal intercourse and rimming due to the possibility of fecal bacterial infection. https://web.archive.org/web/202101/https://old.reddit.com/r/sex/comments/kuyi1z/people_into_anal_stretching_whats_a_good_routine/ Nobody pointed out that anal stretching is a terrible idea. https://web.archive.org/web/202101/https://old.reddit.com/r/sex/comments/knzj5n/i_would_like_some_assurance_on_something/ The OP wrote: "So these are questions for all the ladies.

Do[es] the anal ring become l[o]ose over time because you have anal sex every day?" 1) Nobody pointed out the traumatic risks beyond "micro tears in the skin;" there are much more delicate and pain-insensate tissues beyond the anoderm (which could be described as skin-like) that extends for a comparatively short length in the anatomical anal canal. 2) The top commenter claimed: "The anus can become looser when you have it regularly but tightens back up once you don’t have anal sex for a while." Anal stretching and girthy insertions can permanently damage and weaken one or both anal sphincter muscles at the least, which could result in permanent "looseness." On the other hand, the formation of constricting scar tissue resulting from tearing could make the anal canal seem tighter. https://web.archive.org/web/202101/https://old.reddit.com/r/sex/comments/knakfa/trouble_with_anal_22_f/ The OP wrote: "I have tried everything it seems.

When I watch porn, I only watch anal sex related content, and when I have sex, I'm not satisfied with normal sex, which makes me worried if I can potentially maintain a good relationship with my female partner in the future." Such an obsession could well be considered abnormal and potentially sadistic and/or psychopathic, yet all of the replies were along the lines of "you're just fine." It is quite obvious from studying the anatomy and physiology of the anorectum that the region is very unsuited for girthy and vigorous erotic activities, especially on a repeated/regular basis; it is no substitute for a healthy vagina of an aroused young woman.

I have been in a relationship with this person for over 3 years and while I do love her very much, I do feel like I need anal sex." 1) Nobody mentioned the possibility of one or more preexisting anorectal conditions. 2) No one suggested that the OP has unrealistic expectations due to pornography. https://web.archive.org/web/202101/https://old.reddit.com/r/sex/comments/l713wk/what_are_the_best_positions_for_rough_sex/ The OP wrote: "So tonight I’m going to ask my boyfriend to try rough anal with me for the first time and obviously that’s quite a big thing to do we have had anal before where it’s just been slow but nothing to what I want him to do..." Nobody pointed out that rapid thrusting is always a bad idea, no mention was made of the traumatic risks in particular, and of course potential criminal implications weren't brought up either. https://web.archive.org/web/202101/https://old.reddit.com/r/sex/comments/l3u365/34manal_sphincter_advice_on_tightening/ The OP wrote: "Since mye teens I have loved to play with my anus when I have had the opportunity, using dildos, vegetables, butt plugs and plastic bottles. Though I have often worried about the long-term consequences to health, the sheer enjoyment of this stretching has kept me going. I have not had any problems related to this, until the last few years, where I have noticed a slackening of the muscles «back there». I see some recommend Kegel exercises to tighten the anus, but would like to ask if any of you have had related experiences and if you have advice to give?" There is a reply from one person, who wrote: "The anal sphincter is a muscular ring. Like other muscles it can be stretched to increase its flexibility. This improved flexibility should not damage it or reduce its strength." 1) Kegel exercises will not strengthen the involuntary internal anal sphincter muscle. 2) There are plenty of medical studies pointing out that anal stretching is likely to damage one or both anal sphincter muscles at the least; such damage causes permanent weakening and is associated with fecal incontinence when present in at least 2 of the muscles comprising the anal sphincter complex have such damage. https://web.archive.org/web/202101/https://old.reddit.com/r/sex/comments/l2phzv/wife_cant_handle_anal/ OP's thread title: "Wife can't handle anal." OP went on to write that "she wants to be able to do anal. I'm not trying to pressure her into it or force her to do something she's uncomfortable with. But whenever we try to do it anally, she feels pain just from me being only a few centimeters in, even with lube. Is there something we can do to "train" her anal muscles to not feel pain when we try to do it? Could there be some kind of medical issue going on?" 1) Nobody mentioned the possibility of one or more preexisting anorectal conditions. 2) Nobody pointed out that anal stretching is a bad idea. Several commenters suggested it.

>>fb-DC13Q76E > such damage causes permanent weakening and is associated with fecal incontinence when present in at least 2 of the muscles comprising the anal sphincter complex have such damage. Oops: the "have such damage" part is redundant; it's been dropped. >>fb-TKL2PCAR > I've already completed [preliminary/WIP] commentary on more than what I've posted here (this post included). I'll still take my time, however: Doing so gives me a chance to review what I've already written at a later point and make any changes that come to mind. Currently I'm working on commentary for the 202209 snapshots. Everything from 202208 and older is done more or less, with some bracketed "TODO" exceptions. URLs for archive snapshots from 2023/07 and newer have been added as well; there certainly is no shortage of material fit for inclusion...

https://web.archive.org/web/202102/https://old.reddit.com/r/sex/comments/lfjh58/working_up_to_anal/ The OP wrote: "My girlfriend and I are well versed in PIV sex but we’ve both been wanting to try anal for a while. I’m pretty well hung so we got a toy a bit longer but thinner to practice with before trying for my dick. She can take the toy pretty well with some warmup and lube but we can’t seem to make my dick fit beyond the head and an inch or so. Is there any other ways to get her to loosen up and stretch out?" No one suggested refraining from anal intercourse entirely. https://archive.today/202102/https://old.reddit.com/r/sex/comments/lfjd45/postanal_discomfort_any_tips/ [A different snapshot is referenced due to the other one lacking comments.] The OP wrote: "I (23f) really enjoy doing anal with my bf. He usually finishes inside of me. Afterwards, I go to the bathroom and try to push it back out lol. But even if I feel like I got everything out, I still have some discomfort the following day. I also get gassy and have weird poops sometimes. It sucks because sometimes we both want to do it again the next day but it’s just way too uncomfortable and I need time to recover. [...] Idk what we could be doing wrong, my butt just feels so weird afterwards." 1) Nobody pointed out the possibility of one or more preexisting anorectal conditions possibly caused by their activities, nor did anyone advise refraining from anoreceptive activities entirely and seeing a medical doctor. 2) No one covered specifics about anorectal fragility, nor did anyone point out that significant damage can occur with no pain whatsoever. 3) One commenter wrote: "I have been with bottoms who do have anal almost daily and never have issues." That is highly unlikely. Furthermore, some anorectal health issues can remain undetected unless and until obvious symptoms manifest. https://web.archive.org/web/202102/https://old.reddit.com/r/sex/comments/lerfpf/how_much_anal_is_too_much/ There are many issues here: 1) Nobody made any mention of anorectal anatomy, fragility, and lack of somatic innervation not far inside. 2) The top commenter wrote: "My husband and I have been doing anal anywhere between 1-3 times a week for 20 years. [...] He still fucks me up the ass pretty regularly..." Later in the thread that same person wrote: "As far as I know, my anal sphincter works just fine. I do Kegels regularly[...] I usually wear a heavy buttplug (1.3 pounds) almost daily so that helps maintain my sphincter tone." a) There is more than one anal sphincter muscle, and the internal anal sphincter (IAS) is involuntary: Kegel exercises do not strengthen it. b) Wearing a heavy buttplug daily sounds like a recipe not only for permanently damaging at least the IAS but also promoting at least internal hemorrhoidal prolapse and possibly rectal prolapse as well. 3) Another commenter, TabithaKatherine, wrote: "My husband and I are going to try multiple times anal in a day soon and then take a break and then anal like 5 times in a week and see how I feel." Somebody replied with: "I don't think it's harmful as long as you listen to your body and communicate if there is any pain, etc." to which TabithaKatherine responded: "That's what I've read, too. Plus being properly stretched!" a) It most certainly is likely to be harmful simply due to the fragility of the region involved, not to mention the fact that significant damage can occur with no pain whatsoever. b) Nobody pointed out that anal stretching is a bad idea. 4) Yet another commenter wrote: "Tons of butt sex <> loose stool." Anal intercourse, among other anoreceptive activities, most certainly can cause permanent muscle damage and potentially result in fecal incontinence: the likelihood of that happening increases greatly with insertion of a girthy penis/object especially on a repeated/regular basis. 5) One commenter wrote: "There is no such thing as too much." That most certainly is untrue: one instance of trauma can result in development of one or more anorectal conditions that could render any additional anoreceptive activities of relevance further damaging.

https://web.archive.org/web/202102/https://old.reddit.com/r/sex/comments/ltbcj9/boyfriend_has_a_big_penis_and_anal_hurts_so_bad/ OP's thread title: "Boyfriend has a big penis, and anal hurts so bad as a result." She went on to write: "I've (female) had anal with a couple of past partners and really enjoyed it. I was so excited to try it with my boyfriend, but the first time we tried it it hurt so bad we had to stop immediately." 1) No one mentioned the possibility of some preexisting anorectal condition(s) especially with a history of anoreceptive activities. 2) Nobody suggested refraining from anal intercourse entirely. 3) One commenter recommended anal stretching. https://web.archive.org/web/202102/https://old.reddit.com/r/sex/comments/lqumeq/anal_training_kits_for_women/ The OP wrote: "My wife is interested in doing anal. From what we have read about it you can't just jump in balls deep. Im well endowed and it will hurt her an awful lot. We are looking for a proper anal training kit." 1) No one pointed out that anal stretching is a bad idea. 2) No one suggested that they should refrain from engaging in anal intercourse entirely. https://web.archive.org/web/202102/https://old.reddit.com/r/sex/comments/lnmala/how_many_a_week/ The top commenter wrote: "If you stick a finger in her butt and get her used to that. Then a very small butt plug. A slightly larger butt plug, etc. After a while, you might be able to fuck her ass multiple times a day with no bad side effects. Bottom line, start slow and small." 1) Anal stretching is a bad idea. 2) Rapid thrusting is always a bad idea. 3) It's highly unlikely that any receptive person who engages in anal intercourse "multiple times a day" will experience "no bad side effects," especially if anal stretching and/or rapid thrusting are ever involved. https://web.archive.org/web/202102/https://old.reddit.com/r/sex/comments/lmev2v/scared_of_anal_play_help/ The top commenter, RubyRyder, wrote (reformatted): "There are a lot of fear stories on the internet about anal play or anal sex causing fecal incontinence or prolapse of surgery, etc., etc. Untrue. As long as you follow the rules, you're fine! 1) not too big 2) not too fast 3) plenty of lube 4) Anal safe toys only 5) NEVER use numbing lube." A) Anoreceptive activities potentially can for a receptive person result in fecal incontinence, at least internal hemorrhoidal prolapse, and various other conditions. B) It's rather difficult to determine what constitutes "too big" and "too fast" when there are somatically-insensitive muscles and tissues involved. C) Some lubricants can irritate or damage the rectal lining. D) Significant damage can occur with no pain whatsoever. https://web.archive.org/web/202102/https://old.reddit.com/r/sex/comments/ljo7z2/partner_is_into_anal_but_its_too_painful_to_enjoy/ The OP wrote: "I tried anal and it was one of the worst pains I have ever felt. [...] How can I make anal less painful ?" Nobody suggested the possibility of one or more preexisting anorectal conditions, nor did anyone recommend abstaining from anal intercourse entirely. https://web.archive.org/web/202102/https://old.reddit.com/r/sex/comments/lijf5f/iso_advice_on_anal_health_as_it_pertains_to/ The OP wrote: "I was in an abusive relationship for 2 years and my boyfriend regularly engaged me in anal sex while I was asleep. After I left him I was involved in self-destructive behavior and wound up in another abusive situation. That person forcefully entered me without consent. Sadly, these episodes caused me harm, my rectum prolapsed, and now I have some protruding tissue. [...] Fast forward 6 years later: I am happily engaged to be married this summer and have a loving partner who cares for and supports me beyond belief. He is perfect for me. He has never done anal before and we've been together for over 4 years now. He is not pushing me and never asks, but I want to do it with him badly." No one suggested refraining from anal intercourse entirely.

>>fb-YCJJV3UI > Currently I'm working on commentary for the 202209 snapshots. Everything from 202208 and older is done more or less, with some bracketed "TODO" exceptions. Now I just started on 202306 snapshots, so I'm quite far ahead of what I've posted here as text. Since a PDF file currently can't be included with a post, I'll consider pasting a WIP edition on a pastebin site and referencing that in the near future. I may or may not continue posting more rb&o material as text afterward. Instead (or at least in addition), I probably will start bumping this thread on occasion with material of relevance not present in the referenced 202201 compilation — although some may be added (or reintroduced) to a future edition.

>>fb-X4PL5PC1 Below is what I have so far, with many bracketed "TODO" entries and commentary up to and including 202306 snapshots. Remember that it is an unfinished work-in-progress. I'll reiterate that useful feedback is very welcome and may be used to make improvements for any potential future editions. https://web.archive.org/web/20231212220743/https://pst.moe/paste/xbaqwx In a future edition I might expand the top part to note more all-too-common problematic themes (i.e., those I find myself repeatedly pointing out far too often). Such themes include nobody covering anorectal fragility and traumatic risks (or at least doing so nowhere near sufficiently), one or more commenters suggesting anal stretching, and nobody advising to refrain from anoreceptive activities entirely and perhaps see a medical doctor when the OP and/or a partner may have one or more preexisting anorectal conditions (suggested by the OP mentioning at least one outright, saying pain was experienced, documenting one or more previous anoreceptive experiences that could well have been significantly traumatic, etc).

Why don't you make a website for it?

>>fb-KHRUBFKQ Doing so seems unnecessary when updates are planned to be publicized only infrequently (probably once every 3 to 6 months). If it's clickable links you're after, there are numerous tools which can take plaintext input to create a local HTML file containing them for URLs. Start a thread about that topic on /g/ perhaps.

>>fb-MYATPXCN > Below is what I have so far, with many bracketed "TODO" entries and commentary up to and including 202306 snapshots. Currently I'm working on commentary for 202312 snapshots. I expect to finish by the middle of March at the latest, at which point I'll create a new 202403 edition. Once I catch up to the present time I'll start working on preliminary commentary for material as I add it, and check 1-2 months later to see whether it remains applicable/accurate/comprehensive before including it in any public edition of "rbocommentary" as I've named it. >>fb-XKLIJJ93 There is so much material that could be included in the "trends" portion of Trends & Associations (including the studies that were dropped only to make room for different ones to change things up) that a future compilation may include "Trends & Associations 2," or at least a standalone "Trends" collection. That next version probably is a few years off, though.

>>fb-96HA65D7 Here is the updated 2024/03 edition: https://pst.moe/paste/uolcuo

>>fb-96HA65D7 >>fb-LOA954LV Reddit Bullshit & Omission, along with the commentary, in the nearish future probably shall be shelved indefinitely since the search URL noted below that I was using no longer works at least without javascript ("probably" because that could change and/or a convenient alternative might become evident). Something changed with it around mid-April. I could manually lurk on /r/sex and note relevant URLs, but doing so would be far too time-consuming. https://old.reddit.com/search?sort=new&q=anal+subreddit:sex As for rbocommentary being shelved in the nearish future, first I _may_ create one final update in 2-6 months once I've addressed the many bracketed TODO entries (or dropped the relevant threads) and finished commentary on every included URL up to and including archive snapshots from mid-April.

Heads up: Years ago I used Google to dig extensively for quotable information of relevance, and I found many books with free, image-based previews of the quoted page(s) available from Google Books. I spent quite a bit of time manually transcribing what I saw into text. This was, of course, an error-prone process, and mistakes were made. Recently I added to my collection the PDF version of many of the books cited in the references compilation. I did notice several minor discrepancies (including off-by-one errors for the stated year, a bit of text variance, and non-sequential paragraphs lacking an ellipsis indicating that a subsequent paragraph doesn't immediately follow the quoted predecessor) in the 2024/01/11 compilation that I hope to have resolved in the new 2024/06/11 edition below. I hadn't planned to release another revision this year, but accuracy is quite important, so that takes precedence. Anorectal Trends, Risks, and Anatomy compilation 20240611 https://pst.moe/paste/srucoj OR https://paste2.org/L6dB893j One known minor issue that'll be fixed in the next compilation (along with the image version of A&T): A closing quote is missing from the top line for Forensic Medicine: Fundamentals and Perspectives (2013) - Page 312.

>>fb-LRLTKIVW Whoops, none of the years were changed as yet. In the past I remember seeing conflicting information on different sites regarding the publication date. Perhaps there are regional differences. I'm open to suggestions on that front.

>>fb-UZQWFM76 (OP) > • The "human anus" and the "perineal raphe" articles both depict a female's anus and perineum probably damaged by some kind of major trauma. The English Wikipedia article about the human anus was changed last month, rendering what's quoted above no longer applicable to it for now. The English Wikipedia article about the perineal raphe, on the other hand, remains unchanged so far. From that article as of this post: "The perineal raphe is a visible line or ridge of tissue on the body that extends from the anus through the perineum to the scrotum (male) or the vulva (female). It is found in both males and females, arises from the fusion of the urogenital folds, and is visible running medial through anteroposterior, to the anus where it resolves in a small knot of skin of varying size." Presently not one reference is provided for anything in that paragraph. Further down the article states: "This article incorporates text in the public domain from page 1237 of the 20th edition of Gray's Anatomy (1918)." Looking at page 1237 right now in the PDF version of the book, it's part of a subsection titled "The Testes and Their Coverings." It is talking about a scrotal raphe. There is no mention whatsoever of a visible anterior/anogenital perineal raphe in biological females. "Anatomy of the Human Body" (1918) by Henry Gray can be found here among other places: https://archive.org/details/anatomyofhumanbo1918gray

>>fb-UZQWFM76 (OP) > People with (self-)destructive inclinations, some affiliated with pornography companies, are having a field day with anorectal violence and spreading disinformation. This is contributing greatly to societal decay, aka decadence. The "Diversity, Equity, and Inclusion" (DEI) agenda is contributing to societal decadence as well, at least when it includes promotion of the trans delusion as well as anoreceptive behavior that is foolish, highly dangerous, and likely to be significantly injurious to anyone on the receiving end (especially when people promoting such behavior, under the DEI guise or otherwise, are omitting important details and/or offering overtly dangerous suggestions). "The increasing necessity to address disparities and promote inclusivity in society and within research and medical practice is obvious. In the field of gastroenterology and hepatology, it is vital to realize our responsibility as a community not only in advancing knowledge but also to ensure that this knowledge benefits all persons equitably. Thus, at Nature Reviews Gastroenterology & Hepatology, we are launching a new Series of articles dedicated to justice, equity, diversity and inclusion ( JEDI), entitled ‘JEDI in Gastroenterology & Hepatology’. The Series, the first articles of which are highlighted below, includes review and commentary articles addressing inequities in all aspects of the field and will be continuously updated." "In a Review article, Daniel R. Dickstein and colleagues[2] provide a detailed overview of the physiology of receptive anal intercourse (RAI), a common pleasurable sexual activity that is often stigmatized, and discuss RAI in gastrointestinal disease and related treatments. Normalizing RAI is imperative as patients might experience problematic intercourse that compromises their quality of life and sexual health."

Anal stretching is not a good idea. See also: many medical sources quoted in the Anorectal Trends, Risks, and Anatomy compilation. It's too bad the full study for 10.1038/s41575-024-00932-1 is behind a paywall, as what can be seen from the page arrived at by the DOI is quite concerning and should raise some red flags. And yes, two Nature Reviews studies currently are included in the aforementioned compilation. I'll be going through them very carefully, and may replace them in future editions. I'll also be very wary of Nature Reviews material (and perhaps all Nature publications) going forward.
