If you can only get hard for women, you're straight.
If you can only get hard for men, you're gay.
If you can get hard for both, you're bi.

Twink just means (young) skinny gay dude, a cub is a (young) fat gay dude a bear is a big gay dude.
Femboy is a guy interested in girly things. Can be gay, straight, bi, etc.

Wanting to be the person who takes it up the ass doesn't make you want to be a woman, especially not when you feel the exact same thing when you watch males/femboys/twinks take it up the ass.
