About a 1y and 1/2 ago,When I was 18 I was at a party and had anal sex for the first time unprotected, with a friend of a friend. Trust me, I'm not happy about it because i've never had any unprotected sexual encounter EVER. I've had test for other STDS since then... gonorrhea and clamydia and they were both negative.. I'm almost certain I dont have herpes or hpv, but i will be getting tested for those soon. I was wondering what were my chances of contracting HIV from this person if he was HIV positive (said he was not) and what would be the chances that he had HIV in the demographic of A white..heterosexual male. Although, I have questioned his sexuality. Im so nervous. please help.
