The dentate line, approximately 2 cm above the anal verge, is a major anatomic point when considering the physiology and physiopathology of HD [hemorrhoidal disease] since, distal to the dentate line, the anal canal is lined with squamous epithelium covering the external hemorrhoidal plexus that is innervated by the somatic nervous system and highly sensitive to pain. Internal hemorrhoids are located proximal to the dentate line, where the anal canal is lined with columnar epithelium as in the rectum. This tissue lacks sensitivity due to its innervation by the sympathetic and parasympathetic nervous systems, primarily distinguishing only fullness and pressure. There are typically 3 major anal cushions above the dentate line (right anterior, right posterior, and left lateral) often with some minor accessory cushions between them."

"The anal canal consists of three fibrovascular [hemorrhoidal] cushions that are fed directly by arteriovenous communications. These cushions are supported within the anal canal by a connective tissue framework, and they are important in providing a watertight seal to the anus. The degenerative effects of ageing may weaken or fragment the supporting tissues, and this along with the repeated passage of hard stool and straining produces a shearing force on the cushions [as can anal insertions], leading to their descent and prolapse."

A: No. "Experts say teenage girls are copying what they see in pornography and seeking treatment from family doctors for injuries sustained during “rough sex”. They believe it’s part of the dark side of the sexualisation of the internet generation." ... "According to Reality and Risk, more than 90 per cent of boys and 60 per cent of girls have watched pornography online. Of those videos, more than 88 per cent include physical aggression." ... "Allison Pearson, a columnist for The Telegraph in London, wrote earlier this year that young women are engaging in sex that their bodies are “simply not designed for”. She said a GP she spoke with confessed a growing number of teenage girls were being treated for internal injuries caused by frequent anal sex “not because (they) wanted to, or because (they) enjoyed it — on the contrary — because a boy expected (them) to”." ... "[Dr Meagan Tyler, a research fellow at RMIT University] said research shows women are suffering from faecal incontinence as a result of anal sex and that they’re “uncomfortable” with the assumption that it’s become “the norm”. “That’s the brutal material reality for what it means for these young women’s lives.”" https://www.news.com.au/lifestyle/relationships/sex/boner-garage-posts-a-window-into-the-world-of-sexualised-young-women-online/news-story/f7d83a68c48e378027430fd8e93da349 (June 02, 2015)

[Answer] [...] There's a myth that you can stretch the anus, it doesn't work that way. It's actually relaxing the anus. [...] In fact, a lot of people say anal sex is a great way to prevent hemmoroids because the area is much more relaxed.

"Any break in the ring of the internal sphincter is abnormal, and easily recognized on endosonography. Examination of patients after lateral internal anal sphincterotomy has confirmed that sonographic defects correspond to the site of surgical division. After anal dilatation or stretch procedures there may be multiple defects or fragmentation of the sphincter. A number of studies have confirmed a fall in resting pressure with internal sphincter disruption." ... "Endosonography has made a contribution to the prevention of incontinence by showing exactly what procedures are associated with sphincter damage. Manual dilatation of the anus during anaesthesia is comparatively uncontrolled, and the internal sphincter may be damaged in more than half the patients undergoing such stretch procedures. In 32 consecutive cases sphincter defects were found in 65% with some degree of anal incontinence in 12.5%." "Anal endosonography in faecal incontinence." Gut. 1995 Jul; 37(1): 4-6.

That could in theory be untrue if [such] activities are done with ridiculously excessive care* all the time, every time. * That includes, but is not limited to: ruling out preexisting 𝑎𝑛𝑜𝑟𝑒𝑐𝑡𝑎𝑙 conditions (possibly caused by prior sexual trauma), always using lubricant, avoiding lubricants that irritate/damage the rectal lining, avoiding enemas (all enemas, hyperosmolar or otherwise, probably remove the rectum's protective mucus barrier), always using a condom (particularly in the absence of an enema), never thrusting too rapidly ("too rapid" could vary for different people, at least for the anal tissues), never inserting anything too girthy ("too girthy" also could vary), never using numbing agents (pain indicates that something is wrong -- anally, but not rectally), etc. In practice using ridiculously excessive care is unrealistic -- it'd be more of a chore than a pleasure. Furthermore, both ignorance and misinformation are rampant, porn sets a very bad example that some viewers get ideas from, and people with [self-]destructive tendencies are having a field day.

4chan /gif/thread/13721666 18 Oct 2018 04:02:49 No.13758673 The human 𝑎𝑛𝑜𝑟𝑒𝑐𝑡𝑎𝑙 region is anatomically and physiologically very unsuited for girthy, vigorous receptive activities. The single short-term benefit, _potential_ pleasure, is greatly outweighed by the many short- and long-term health risks for the receptive person. (Quoting post 13749283) > getting fuarrrked up the ass really hard is bad Even thrusting with a modestly girthy penis much less vigorously than "really hard," especially for a prolonged period of time, is likely to result in damage. It is very, very obvious from studying the anatomy and physiology of the 𝑎𝑛𝑜𝑟𝑒𝑐𝑡𝑎𝑙 region that, even in the best of health, it's nowhere near as durable as the healthy vaginal canal of an aroused young woman. 4chan /gif/thread/13721666 18 Oct 2018 04:03:21 No.13758677 [...] - Ruling out preexisting conditions each and every time is ridiculously excessive (and defecation trauma alone can cause such conditions to be present, never mind erotic trauma). - Trying to determine what constitutes too girthy and/or too vigorous is not really feasible outside of a laboratory environment (stretch damage at least to the internal anal sphincter muscle may not elicit pain sensations; damage to the rectal lining does not elicit pain sensations; connective tissue damage may not elicit pain sensations; etc).
