Most likely straight or bi, but He could even be a gay dude (yeah I've met them, they are few and far between in my experience, but they certainly exist - but let's not get into cultural stereotyping lol).
He's born with it and He knows he OWNS you. He gets away with whatever He feels like doing cuz He knows the bitches jump whenever He snaps his fingers. He doesn't have to beat His chest, shave His chest or have an expensive ride, like all the other douchebag tools out there trying to pick up girls - no he doesn't give a shit about your approval. A real Man doesn't have to go to an effort to wield His power over His bitches.
