Question: what are the chances of getting hiv with protection?
Answer: And if an HIV-negative person bottoms for an HIV-positive top who doesn't use any protection but does ejaculate inside, the chances of HIV transmission are, on average, less than 2 percent. Specifically, it is 1.43 percent, or 1 out of 70. If the guy pulls out before ejaculation, then the odds are 1 out of 154.
