I'm emotionally and physically attracted to men, but I'll sleep with or follow an intimate narrative with a girl here and there. I don't much identify as bi, but technically I guess I am. Pan probably makes more sense.
Also, gay doesn't have anything to do with masculinity. I'm small and sensitive and educated, but I'll attempt to take anybody in a fight if the circumstances demand it. I can sleep anywhere and survive almost anything, and I'm only really scared of the past. I'm pretty masculine by a lot of definitions, but that's not caused by or a product of liking girls.
I get laid far less easily since transition, so, ah, yeah. It does create some barriers. I won't deny that.
