I recently performed oral sex on my ex boyfriend who was sexually active with another woman. The girl claims to be "clean" and disease free but I can't be too sure. The two had unprotected sex. Although I did perform oral sex, he did not ejaculate in my mouth. But a tiny amount of pre ejaculatory fluid went into my mouth. I did not have any visible cuts or sores. It is too soon to be tested but I am just very anxious, what should I do?

It is possible that HIV could be transmitted through pre-ejaculatory fluid (the small amount of fluid that comes out of the penis during sexual contact before ejaculation). HIV can be isolated in pre-ejaculate and there is evidence that individuals have been infected by a male through sexual contact without ejaculation. However, infection is much more likely to occur with ejaculation and during receptive anal or vaginal, not oral, sex.
