The fact is there is a large increase of AIDS in the hetero, non-drug society. This fact leads one to believe that some blood is being tainted,however; most studied indicate that male and female heteros are at as great a risk as other groups.
Folks, you do not go to bed with just one person, you go to bed with every person they have gone to bed with, and many are bi, or are drug users, or have been with either.
Now, if the urge to copulate is so strong as to be irresistible, then us a condom. I would urge folks to not put themselves in a position that either would be necessary. Just my morality speaking out here though, you must attend to these situations according to your own.
Blessings
