it is a fact that lesbian men who enjoy eating thier own bodily fluids in turn become that of an crazy mummbo jumbo. take heed my son and you shall not eat thine own man gravy. GO FOR THE WIN!!!
semen will NOT kill you, even if you're straight or if it's your own. It is a bit strange maybe but don't worry about it. If you like it, then maybe girls will too.
I think it's very normal to wonder what your own stuff (or semen in general) tastes like. Actually tasting it does NOT mean you are gay or even close to it (although you may also be gay as an aside). I'm a girl who is famous for asking point-blank VERY personal questions and I've asked more than 30 men if they ever tasted their own. Most of them admitted they had at some point out of curiousity. Only 2 of those who said yes are even gay.
Go ahead and try it, you might like it!
