Hi,
New here, but would like to think that a guy could engage in oral with another guy, and not be "homosexual". I myself am attracted to women, but would not turn down the opportunity to have sex with a guy. I, unfortunately have never had the opportunity. My bad luck.
Anyhow, i also don't think being presented the opportunity to have sex with a guy would shift or change my attraction for women.
So i guess what i am saying is sex and attraction are different. And i think two guys can fool around together without being "gay" or whatever term you want to use.
