I worked with a gay man who I became friends with. He is the only gay person I was ever comfortable asking personal questions of. I asked him when he found out he was gay. He told me of his first encounter. He glamorizied it, but he had been molested by an older boy several times and had begun to think of sex as only between 2 men. I think this article is on to something.
I think if you probed the backgrounds of most “gay” men, you would find similar stories of grooming and seduction by sodomite pederasts.
I see that connection between molestation and the victim growing up gay but I also think for other gays that were not molested, there is some kind of dysfunctional relationship between the mother/father and child. The mothers of these gay men are totally dominate in the marriage, sometimes violent and the father is often weak.
