I am a straight male taking prep. I only have vaginal sex with female. My partner is hiv positive. I always hear we cannot kill hiv virus. If we take prep it builds a wall around our t cells so hiv virus cannot replicate in our cells. My question is, if hiv virus go in the body of person on prep, it will hit a wall created by prep, and cannot replicate. But the virus still in our body and cannot be killed. Does that mean one day we get off prep, we lose the wall around our cells, the hiv virus can jump in our cells and start replicate again? or does it die itself if it cannot replicate after sometime? thank you, i cannot find the answer any where on the internet.
