worried

[Bionca]

I've done HIV education for GLBT youth. The short answer is, it is highly unlikely you are positive the way you described the encounter. While anal sex causes tiny cuts in the anal wall and there is some blood, the chance of infection from such a small amount is very slight.

Everyone... and I mean EVERYONE should use protection 100% of the time no exceptions until both you and your partner have tested negative for 6 months. Even then, I'd only stop if I really trusted the person, since not everyone is as faithful as they let on. All penetration needs to be done safely anal as well as vaginal .. even oral can be risky.

So, chances are greatly in your favor that you are fine. You had, what sounds like, brief contact that was unprotected. Your partner is likely being truthful and is negative as well. It is normal to be worried, and I have been there myself under slightly different circumstances.
