Personally in my experience talking to quite a few homosexuals its almost always people with severe physical abuse or sexual trauma in their past. Its almost 100% occurence. I think it boils down to feeling like they dont fit, something is wrong, its a destructive response to their true self and an attempt to gather a recreate their identity in a safer situation where they feel more comfortable. 5/5 male homsexuals i am friends with experienced male to male sexual abuse in their past. There seems to be a distince link, not necessarily 100% but with a very high occurrence between struggles as a child and homosexual behavior as an adult. Just my observations and experience
