Add in an inattentive father, the two I know had both.
I have observed the same situations amongst my acquaintances.
I saw him last year and he told me that after high school he joined the USMC...told me the reason was he wanted to get rid of his mother's internal voice and replace it with a positive one, like that of a drill sergeant.
This guy turned out to be quite different than his childhood might have indicated.
The classic psychological recipe is the overbearing mother and/or the absentee or distant father, the other predominant factor is same sex sexual abuse. Add in the other kinds of abuse like mentioned in this article and you have a potential homosexual. They’re not born that way.
I knew a man who had come out of the homosexual lifestyle and counseled those wanting to leave (both male and female). He said his own experience and the universal condition of those whom he counseled was a broken relationship with their father.
Lots of different reasons, not always the father's fault, sometimes broken only on the offspring's side. But, according to him, a broken relationship with the father was always there and always needed healing.
