Between two individuals gay or straight a committed relationship, I can see it. The power dynamic and bonding nature of it must be euphoric. There's also a major trust fact that will bring the two parties together. Never done it because I do not want kids. Condoms all the way. Besides STD are making a comeback in a Yuuuge way.
i know i'll probably get flamed for saying this but as someone who has my own experiences to reference as well as straight male friends, female friends, and gay male friends and gay male co-workers it is apparant to me my gay male friends/co-workers have sex with more people in a given month than my straight male friends and straight female friends.
not sure if it is just too easy or their goals are different in that the end goal isn't marriage and child bearing? or maybe the fact they can't get preggers makes them less careful but can still get std's?
i guess what i'm saying is i don't thing there are std's sent to get the gays or any conspiracy i think statistically if you play with fire more often you'll be burned
