What are the risks of contracting HIV during condomless sex?

January 20, 2008
If someone has unprotected oral and/or anal sex with no ejaculation or blood contact, what are the chances of HIV transmission?—Anonymous
The answer to your question comes on two levels--the theoretical and the real. Theoretically, no. It really can't. HIV is spread through the mixture of bodily fluids (blood and semen being the two biggies). If they aren't exchanged then no transmission can take place.

Realistically, however, you don't need to blow your load in a bloody gash on someone's arm to spread the virus. Microscopic tears occur during most types of sex (the more vigorous the sex, the more tears that occur). This can pass HIV from the bottom to the top from the exchange of microscopic amounts of blood, or from the top to the bottom from HIV found in pre-cum. You really can't have sex without these cuts, so the possible exchange of blood and semen cannot be prevented during unprotected sex.

If numbers are your game, the January 2002 issue of the medical journal Sexually Transmitted Diseases said that receiving oral sex with no condom from a stranger with an unknown HIV status involved a 1 in 200,000 change of spreading the HIV virus. Double that risk existed for the person giving the virus. This risk for the "sucker" can be minimized if the "suckee" does not cum in his mouth.

For anal sex, topping that same stranger would give you a 13 in 200,000 risk of contracting HIV. Bottoming for him with no condom for the same stranger involved a 1 in 2,000 risk of contracting the HIV virus. That's a risk that falls to 1-2.5 in 100,000 if use a condom, incidentially.

If your partner is HIV, multiply all of the above risks by 43.

None of the statistics answered your question regarding sex without cumming inside one's partner, but hopefully those numbers will give you a ballpark idea of what your risks are.—Aaron Lawrence
