Answer to someone who asked how he could tell if his best friend is gay:
The only sure way to know is to ask. He may be gay. He may be straight. He may be bisexual. He may like looking at the avatars' pixellated butts. He might just be femme. He could just be odd. He might be gender-variant. He may like to crossdress. Only way to know is to ask him. Assure him that you're cool with him either way, but that you'd just like to know.
