Hi. I am a female who had unprotected sex with a male partner last week. He said he is clean, but I know he has other female partners (I'm not sure if he uses protection if with them, so who really knows if this is true). I haven't had sex in over a year and was tested 6 months ago. I'm very nervous, mostly about HIV contraction. What are the odds from this singular incident? It was also slightly painful and rough - I'm not sure if there were any small micro-abrasions that that could increase transmission?
