Why Anal Sex Is More Dangerous For HIV Than Vaginal Sex?

Unprotected anal sex is essentially more dangerous as compared to vaginal intercourse since the very lining of the anus as well as the rectum can be more easily broken than the lining you find in the vagina. Keep in mind factors like the high concentration seen of white blood cells in the region of the rectum, coupled with this danger of cuts as well as that a basic function of your body's rectum is necessarily to absorb fluid.

Thus, unprotected receptive anal sex is deemed the topmost risky sexual behaviour when it comes to HIV transmission. This risk for unprotected anal sex would be considered higher in cases where the uninfected person acts as the receptive one.

Note that unprotected anal sex would be deemed as high risk activity for not only homosexual male but also heterosexual couples. Research seems to indicate that while gay men are more inclined to engage in the act of anal sex, heterosexual couples on the other hand are more prone to not using condoms when doing so.
