How can I prevent HIV transmission and STDs during anal sex?
Unprotected anal sex with a person who has HIV or another STD, or whose HIV or STD status you do not know, is the highest-risk sexual activity for both men and women. The walls of the anus and rectum are thin and have many blood vessels than can be injured during anal sex. Injured tissue in the anus and rectum can expose you to HIV and other STDs. Male latex condoms used with a water-based lubricant reduces the chance of tissue and skin tearing and lowers the risk of transmitting disease during anal sex. However, even with lubrication, male condoms fail more often during anal sex than during vaginal or oral sex. Female condoms should not be used for anal sex, as they do not provide adequate protection. Because use of the female condom during anal sex requires removal of the inner ring, the female condom is unlikely to stay in place during anal intercourse.
