Even identical twin can recieve different portions of hormones from their mother in the womb. That might explain it.
Almost 40 Years ago, a homosexual co-worker told me he could tell that I was a homosexual teen-ager and that my fate was sealed. He suggested that I should just get it over with and spend the night with him. He would have really enjoyed using the hormonal washing argument on me if it had been around.
His parting statement was that I when I reached my 40's, I would find myself fleeing the straight life because homosexuality was my destiny.
I perceive that there was a time very early in my life when I was susceptable to such experimentation (out of ignorance) and such experimentation might have set me on the wrong course but I am convinced that the problem is not one intrinsic to ones own biology.
