positive bottom with negative top..please answer me

Sep 12, 2012

Hi I am a positive undedectable bottom and I had unprotected anal sex with a negative top. It didn't last long - a few minutes- and he didn't ejaculate. I was bleeding a bit though a few hours before and I have been treated for anal warts last year. What are the risks of me having transmiting the virus ? He started taking PEP roughly 57 hours after exposure. Please please answer me, I have been asking this question so many times...

Response from Dr. Hightow-Weidman

Hello there- Many factors go into asking this question and there isn't an exact number I can give you. My overall response would be low (but not nothing) given that you are undetectable, he was the top (although you were bleeding) and he is now on PEP. People with undetectable viral load in the blood have a much lower chance of transmitting HIV to others, but much of these data come from heterosexual couples. Is it totally impossible for such people to transmit the virus? Probably not and some of this may have to do with breaks in HIV therapy and possibly transient increases in the amount of shed virus, like during another sexually transmitted infection (this is theoretical). In my opinion I would agree with continuing PEP and getting tested. Take care, LHW
