>pre-op female to male transgender
Pre-op? So, does that mean you're planning to eventually get an operation, or what? Sounds pretty unnecessary/silly to me. You're either a transgender or not.
As for advice: Homosexual guys are made of the same stuff as heterosexual guys. I agree with >>11 that >>1 should just find a willing straight guy, and avoid the expense and stress of a transgender operation (which I, personally, doubt she ever SERIOUSLY considered).
