About 4 months ago, I had unprotected oral sex with a guy that I know has been with at least a few other girls. The question of protection or other sexual partners never came up, although he knew that I was a virgin and that he was not. I was worried about my risk for HIV, again, I do not know his history. I have had no testing or symptoms as of yet....
