The way I see it, you love who you love. That can change, yes. Is it likely? No. People are thick headed. Do I think homosexuality is wrong? I don't care, really, so long as them dudes don't hit on me. Do I think homosexual marriages should be banned? Again, I don't care either way, but don't make a big freaking deal about it, and don't make the best man at your gay marriage.
Love is mental and physical attraction toward another. By nature, we're attracted to the opposite sex. It makes sense. The purpose of sex is procreation. That's the only reason. It feels good, yeah, but if it hurt, would you still do it?
As a straight male, I'm doing what I was made to do; make babies. Plain and simple.
I don't mind gay guys or lesbian gals. That's your thing. You do it. What happens in the bedroom should stay there. I've got no problem with that. I know quite a few bi and gay guys and they're cool. They're not going on about it all day long.
It's the one's that expect you to be okay with it and make a deal out if it that make me uncomfortable.
