I don’t think either precludes the other. In other words, not mutually exclusive. You may have seen me mentioning my neighbors son before. Plays with butterflies, drives pink barbie Jeep, looks feminine. Dresses in colorful clothing. Kids is 4. Can it be the parents? Their daughter is a tough Tom Boy that’s a killer soccer player!
I think there are few that are wired that way, but I think they are a relatively small subset of those who consider themselves gay. I also believe that being molested as a child can “flip the switch.”
