Hi and welcome to HCM There are a number of health risks with anal sex, and anal intercourse is the riskiest form of sexual activity for several reasons, like anus lacks the natural lubrication the vagina has, tissue inside the anus is not as well protected as the skin outside the anus, anus is full of bacteria. Anal sex can carry other risks as well. Oral contact with the anus can put both partners at risk for hepatitis, herpes, HPV, and other infections. For heterosexual couples, pregnancy can occur if semen is deposited near the opening to the vagina. Even though serious injury from anal sex is not common, it can occur. Bleeding after anal sex could be due to a hemorrhoid or tear, or something more serious such as a perforation (hole) in the colon. If you engage in anal sex, it is always important to use a condom to protect against the spread of infections and diseases.
