How likely are two healthy boys to be infected with AIDS without protective measures?

First, you should make sure whether you use condoms and other safety measures. If you do this, the probability of infection is almost zero. If you don't take safety measures, you will both be healthy and won't be infected, but if he is a virus carrier, you may be infected. In addition, if he is a virus carrier and has bleeding during sexual intercourse, the probability of contracting AIDS will be even greater. I'm not worried about this, but worried.
