The human anorectum is highly unsuited for many all-too-common receptive activities. That is due to the fragility of the anorectal region. Contributing factors include:
• Anatomy — Not far inside there are very delicate and pain-insensate tissues (including simple columnar epithelium, a lining that some enemas and lubricants can inflame and even remove).
• Neuromuscular physiology — The internal anal sphincter is involuntary and relaxes with rectal distension. The external anal sphincter and puborectalis completely relax as a person bears down, causing hemorrhoidal cushions to engorge and increasing the cushions' fragility.

There are many potential traumatic consequences of such activities, including abrasion and tearing; damage to muscle and connective tissues; colorectal perforation; hemorrhoidal disease, such as internal hemorrhoidal prolapse; rectal prolapse (originating from further inside); and inflammation. All of those can lead to even more issues: bacterial infection followed by abscess / fistula / life-threatening systemic sepsis; fecal incontinence; anatomic stenosis (narrowing due to constricting scar tissue called a stricture); and one or more anal skin tags (scar tissue e.g. from a healed tear, a sentinel tag associated with a chronic anal fissure, or a remnant of external hemorrhoidal thrombosis).

'Boypussy' and variants are idiotic terms. A young woman's healthy vagina—especially when she's aroused—is much more durable and better-suited by far for girthy and vigorous receptive activities than the human anorectal region.

> Not far inside there are very delicate and pain-insensate tissues (including simple columnar epithelium, a lining that some enemas and lubricants can inflame and even remove).
1. Some (perhaps even many common) lubricants and enemas can do more harm than good.
2. Considering that the simple columnar epithelium above the dentate line is very delicate and does not elicit pain sensations when damaged, thrusting that is not too rapid—if that is even possible to achieve—may be very slow indeed (and then there is the possibility that an enema and/or lubricant removed the lining entirely: how does that factor in to the rate of thrusting question?). As I posted years ago elsewhere:

(Quoting myself)
> At best, anal sex and significant anal-insertive activities accelerate or guarantee the development of anorectal health problems.
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.

Fuck you for spamming 9chan /pol/ and generally being a retard and fuck anyone responding to your shitty bait thread in a serious way.

1. Ultimately this is not about me.
2. 9chan currently does not have a /pol/ board. Rather, it has a /bestpol/ board. I might have posted on it a few times at most.

Here's a longer summary with even more medical sources:

Traumatic risks of human anoreceptive activities include inflammation, mucocutaneous abrasion and tearing, muscle and connective tissue damage, hemorrhoidal disease, rectal prolapse, and colorectal perforation. Sequelae may arise, such as hemorrhage/hematoma, ulceration, bacterial infection followed by abscess / fistula / systemic sepsis, fecal incontinence, anal skin tag (remnant of external hemorrhoidal thrombosis, scar tissue perhaps from a healed tear, or a sentinel tag indicating a chronic anal fissure), and stenosis (narrowing; possibly anatomic due to constricting scar tissue called a stricture). One instance of trauma can lead to multiple complications. Cumulative damage and preexisting conditions are concerns as well.

~2cm beyond the anal opening at the pectinate/dentate line, the epithelial lining transitions from stratified squamous (anoderm) to simple columnar in part of the narrow surgical anal canal, continuous with the rectal mucosa. This simple columnar epithelium is very fragile and easily damaged especially if its mucus barrier is removed by an enema or otherwise impaired. Furthermore, some enemas and lubricants can inflame the lining and even cause it to slough off entirely. Injury to this lining alone does not elicit pain sensations, so resultant problems may remain undetected without one or more obvious symptoms.

Neuromuscular physiology also contributes to anorectal fragility particularly for girthy and vigorous insertions (which are objectively foolish and very likely to be significantly injurious). The involuntary internal anal sphincter relaxes with rectal distension. The puborectalis and external sphincter completely relax when a person bears down, causing hemorrhoidal cushions to engorge and become more susceptible to injury by potentially-bidirectional shear force.

Also, several English-language Wikipedia articles have had major issues for years that need to be addressed:
• The article about the human anus has an image of a human female's anus and perineum that probably were damaged by some kind of major trauma. Human females beyond developmental stages in the womb should lack an externally-visible perineal raphe, or seamlike union/ridge, in the anogenital region between the anus and the vagina; the bulbospongiosus muscle is separated in them and does not form a persistent, visible midline raphe as it may in males [References: Anatomy & Trauma].
• The article about the perineal raphe asserts that both males and females have a visible perineal raphe arising from fusion of the urogenital folds. No cited source supports that claim.

The article about anal sex ...
• lacks a neutral point of view — an essential component of Wikipedia's presentational philosophy. It does not present even one _scientific_ opposing perspective, giving readers who are not exposed to more balanced sources the impression that opposition is limited to irrational religious positions. One such scientific perspective: The human anorectum is very unsuited for many all-too-common receptive activities due to the region's anatomy and physiology. The single short-term benefit, _potential_ pleasure, is greatly outweighed by the many short-term and long-term health risks for the receptive person. [Rationale: Anorectal Risks 1-3]
• does not mention the normalization of blatantly injurious anoreceptive violence in pornography featuring real people.
• fails to point out that "hemorrhoid" is an ambiguous term, sometimes referring to pathology and other times to normal anatomy.
• contains a logically-fallacious appeal to nature: "natural" is not necessarily good or desirable, nor is "unnatural" necessarily bad or undesirable.

Those flaws are contributing to rampant anorectal abuse and misinformation facilitating such abuse.
