How do you get bored of having sex with women by the time you are only 19?
I’m guessing that Charlie hit the casting couch to win parts and was changed by the experience, as most men would be if they tried homosexuality.
Never done it and would never try it, but I think there might be something that changes in men to be more open to it once they do try it.
I think that would be true if they get them young and groom them to accept it. I don’t know any grown men that would bend over for the other team. None.
