There's also risk factors to take into account…. As I've said before, the biggest factor in the equation is the HIV+ person's viral load.... There's also other factors, such as the length and roughnes of the sex, and whether or not tearing of the bodily (anal or vaginal) tissues occurrs. That being said though, proper education is a good start and not having to fear it because you don't understand it. 🙂
I completely agree with the concept of a little education goes a long way.
