Study Says Contracting HIV, Anal Sex Linked
William SaletanAccording to data released earlier this year by the Centers for Disease Control, the probability of HIV acquisition by the receptive partner in unprotected oral sex with an HIV carrier is one per 10,000 acts. In vaginal sex, it's 10 per 10,000 acts. In anal sex, it's 50 per 10,000 acts.
William SaletanA CDC fact sheet explains the risks of anal sex. First, "the lining of the rectum is thin and may allow the [HIV] virus to enter the body." Second, "condoms are more likely to break during anal sex than during vaginal sex." These risks don't just apply to HIV. According to the new survey report, the risk of transmission of other sexually transmitted diseases is likewise "higher for anal than for oral sex," and the risk "from oral sex is also believed to be lower than for vaginal intercourse."
