Anal sex is linked to an increased risk in fecal incontinence, aka pooping your pants at least once a month. (Yup, you lose control of your bowel movement!) This is according to a new study published in The American Journal of Gastroenterology, and the finding applies to men and women.
Researchers at the University of Alabama at Birmingham Department of Medicine analyzed data from the 2009 to 2010 cycle of the National Health and Nutrition Examination Surveys. That's 4,170 adults from 20 to 69 years old, and the researchers found that the 37 percent of women and five percent of men that had anal sex were more likely to experience fecal incontinence once a week than people who don't engage in anal at all.
"Anal intercourse could dilate and eventually stretch the internal and external anal sphincters leading to damage of these structures, as demonstrated by the lower resting pressure," the researchers state. "This lower pressure and possible damage to the internal and external anal sphincters could lead to fecal incontinence via muscle atrophy and sensory deficits." In other words, engaging in anal sex damages that part of your body that controls bowel movement, resulting in anal leakage.
However, the study didn't say how often engaging in anal sex can do such a damage to one's anal sphincters, and it didn't ask its respondents how often they have it. So if you don't want to do it, here's all the more reason not to. But if you still want to have anal sex and avoid pooping your pants, make sure you use LOTS of lube, and do regular Kegel exercises.
