Is it normal that you're gay?
If you were ashamed of being in love with a man and suddenly discovered these new feelings, something that you only allowed to happen because you thought he was gay, and you're hoping to exact revenge, but then you found out he was straight, then you wanted to get even, so maybe you put a mask on someone and tried to convince yourself the sex you were about to have was with yourself but it turned out to be him and all you ended up doing was proving that your feelings were real, then I might say something like, "Homo much?"
