You're not straight, you're not even bi. If you were bi, you would still think about pounding pussy and getting women, but you only think about men. More specifically, men’s throbbing cocks. You only get hard and stroking and gooning over the thought of men using your holes. You're gay, regardless of how long you've been in the closet, how people perceive you and for how long you've repressed this part of yourself.
