If I am not sexually attracted to males, is it still gay to penetrate them anally because there aren't any girls who will let me bang them?

Yes, "ratarded".

A lot of straight people had sex with the same gender at least once in their lifetime. It doesn't make them gay. Being gay comes from your preferences. If you're a man who's sexually attracted to girls but not guys, then your straight. It's as simple as that.

Sexuality is about who you're sexually attracted to, not who you have sex with.

We'll if you really liked it more than with girls it's very questionable or you could be sexually curious I suggest bisexuality but unless I knew you I don know for sure

no dummy, homosexuality is a sexual orientation, so if you have sex with a guy even though you are not sexually attracted to males, that still makes you heterosexual

many guys in prison gang rape other prison inmates, but it has nothing to do with sexual attraction

that's like saying if i remain celibate all my life, does that make me asexual??

most people who are celibate like buddhist monks or priests choose to be like that, but that doesn't mean they don't have sexual attraction.

Yes. Why don't you visit Lily Palm and her five daughters until you grow up enough to be tolerable to women?
