Most importantly, guys don't turn down sex. A guy will not get all huffy and slap you for asking for road head. He will punch you in the stomach if you drink the last beer. That's understandable. But you will then respond in kind by punching him in the stomach. One of you will cave and drive to the store for more beer. The problem will then resolve itself as you both drink and laugh about the fight extensively. That sounds preferable to weeks of analyzing every bump and vocal tic used in said argument.
Being gay does have one drawback, though. It's slick, cylindrical and about 8 inches if you're lucky. Apparently, if you're gay you have to enjoy some degree of strange penis interaction. I say strange, because playing solitaire in the shower is probably more heterosexual than actually having intercourse with a woman. Cock fear aside, I'd still rather give Tiger the old tug and pull than babysit his vampire children. Vampires really freak me out.
