Anal sex can exacerbate hemorrhoids and therefore result in bleeding; in other cases, the formation of a hemorrhoid is attributed to anal sex. If bleeding occurs as a result of anal sex, it may also be because of a tear in the anal or rectal tissues (an anal fissure) or perforation (a hole) in the colon, the latter of which being a serious medical issue that should be remedied by immediate medical attention. Because of the rectum's lack of elasticity, the anal mucous membrane being thin, and small blood vessels being present directly beneath the mucous membrane, tiny tears and bleeding in the rectum usually result from penetrative anal sex, though the bleeding is usually minor and therefore usually not visible. By contrast to other anal sexual behaviors, anal fisting poses a more serious danger of damage due to the deliberate stretching of the anal and rectal tissues; anal fisting injuries include anal sphincter lacerations and rectal and sigmoid colon (rectosigmoid) perforation, which might result in death.
In Japan, records (including detailed shunga) show that some males engaged in penetrative anal intercourse with males, and evidence suggestive of widespread male-female anal intercourse in a pre-modern culture can be found in the erotic vases, or stirrup-spout pots, made by the Moche people of Peru; in a survey, of a collection of these pots, it was found that 31 percent of them depicted male-female anal intercourse significantly more than any other sex act. Moche pottery of this type belonged to the world of the dead, which was believed to be a reversal of life. Therefore, the reverse of common practices was often portrayed. The Larco Museum houses an erotic gallery in which this pottery is showcased.

Repetitive penetrative anal sex may result in the anal sphincters becoming weakened, which may cause rectal prolapse or affect the ability to hold in feces (a condition known as fecal incontinence). Rectal prolapse is relatively uncommon, however, especially in men, and its causes are not well understood. Kegel exercises have been used to strengthen the anal sphincters and overall pelvic floor, and may help prevent or remedy fecal incontinence.
The emotional overture I feel before boarding a roller coaster is about the same as I feel right before embarking on anal sex: excitement, followed by mild hesitation and nervousness. But! The thing about every single roller roaster ride I've been on (so far) is that I've loved them all. No matter how many butterflies are tap-dancing on the bottom of my stomach as the ride lurches up a steep hill, the thrill I feel at the end of the ride is always worth it.
