Is it normal to rub on guys and like it if im not gay?

everytime i go to a club or bar i tend to try and walk through crowds of dudes who are talking or what have you just to brush my genetalia on them... by the way i am not gay atleast i dont think i am. something about getting close to a guy and smelling him while i rub pelvises with him just makes me go INSANE!!!! i think its just a turn on of mine but im not gay. i like to stare at girls dancing too but id slightly like doing this better. is this gay am i bi???
