Um, I don't know... there's a very fine line between jealousy and admiration.
I'm bi and a guy... but there's typically something I admire in a guy that makes me attracted to him. And things I admire in a guy usually get incorporated into my own personality and behavior somehow, i.e. I want it for myself. I do get quite jealous sometimes of the guys I'm attracted to, also. So I'd have to agree with MissConstrue, from the guy point of view.
So I wouldn't be so quick to dismiss your potential homosexual side if I were you.
