Ah, you took it wrong. :D It's not that they're "indifferent" to gender, it's that some of them are SERIOUSLY SO DEEP IN THE CLOSET THAT WTFFFFF OMG they may never come out. In all the fandoms I'm active in, there have never been any official declarations of THIS CHARACTER IS COMPLETELY STRAIGHT/GAY, and as long as there aren't any, I figure I'm good to do whatever I want with their preferences.

This isn't to say that I'm going to turn uh, like, Seifer into some kinda flaming gay queer just because he's not OFFICIALLY CANONLY -ONLY- STRAIGHT. He's going to act like Seifer acts. Bash people, not let anyone emotionally close to him, generally be an arrogant ass. But if someone somehow DOES get close? It'd be way -easier- for a girl than for a guy, but the possibility would be there. That a bit clearer?
