I don't know if that is reassuring or not; I'm entirely comfortable with my choices. I was also barebacking frequently with other poz guys for over seven years before meeting my partner. I wasn't on treatment and not all of them were either. I didn't develop resistance. I don't know if one can tell anything from a single case, and I have no medical training, but I just don't buy that the situation that you are describing is risky. I think driving to work in rush hour traffic each day is more dangerous.....but what do I know?
