where and how does hiv infection occurs?
Apr 10, 2002

does anal intercourse with an hiv+ automatically spell infection? is there hiv virus present in precum? can hiv virus enter thrugh the head of a perfectly healthy pennis?

Response from Mr. Kull

Exposure does not equal infection. Several factors need to be present for HIV to be transmitted, some that are observable and some are not. If you have unprotected anal sex with an HIV infected person, transmission is possible. If the receptive partner is negative, ejaculation increases the risk (these things are or can be observable). However, other factors, like the infected person's viral load and the negative person's immune response, could have an impact on the likelihood of transmission. These factors are more difficult to measure, at least without access to a laboratory. Condom use is recommended for anal sex to eliminate the crapshoot (sorry for the pun) you would be engaging in if you don't use condoms.

HIV can be present in precum and a person could be infected by exposure to precum alone.

HIV does not penetrate the head of the penis. The mucous membrane lining of the urethra (the tube you pee out of) is susceptible to infection. It is also possible that the lining of the foreskin of an uncircumcised person could be susceptible to infection.
