Hi

A week and a half ago I had this one night stand with this guy and now I am a bit worried about the possibility of contracting HIV. Basically, what worries me is, that at first he tried to enter me without a condom (he did not get in, but did touch my anus with his penis without going in). Then I told him to put a condom on and he did. But my worry is that is it possible that he left some precum on the opening of my anus and I might have contracted HIV via that? Hope someone will know the answer to that. I will go and have myself checked in three months time anyway (after the window period), but would be great to know the chances of getting HIV. Thanks K.
