With respect, I doubt that very mcuh.
You don't know my cousin or the environment we were raised in. He and I had very extensive discussions about his homosexuality. He was very forthcoming with infomation about his sexuality.
He told me that as teenagers when the male cousins viewed the usual Playboys etc. he was actually looking at the male models. According to him the sexual attraction to males began at puberty.
There was no one in our environment to recruit him.
