When stumbling across the question: Is homosexuality a mental disorder? I realized that it is very close to a personal question that My wife and I (mostly me to be fair) about the source of homosexuality in sexually abused children and young adults. First, as I know this is a sensitive subject please understand that my goal is understanding and not offence. I am simply trying to understand a situation that may or may not arise, in our lives. Let me explain, and hope that this will make this question clearer. My wife and I are currently in the process of becoming Foster parents. One of the things we need to do, is to be honest about where our personal lines are. For an extreme example you don't want the leader of the KKK to be tasked with raising African American children. However a lot of our interactions are focused on finding much more mild cases of Oh I didn't realize that would be a problem for us, I never thought about it that way.In recent classes the topics of homosexuality and sexual identity have come up. And while I have no problem with homosexuality as a choice or a pre-disposition. I wonder about homosexuality as a result of trauma. For example, A teen that decides that he is homosexual, under normal circumstances is fine by me. If it is an active decision and preference then it doesn't matter, it's his choice. If it's a passive trait (for example genetic) then again it doesn't matter. It's like being left handed. It just is, move along. This is summarized for brevity, obviously. But that is a good summary of how we (both my wife and I) feel. But one of our responsibilities as a Foster parent could include caring for sexually abused children and teens. The question is how can we, or should we try to differentiate between homosexuality as a response to trauma or naturally occurring homosexuality?
How can you tell the difference between natural homosexuality and trauma related homosexuality
sexuality
There is no evidence that trauma influences sexual orientation.  I hope that you would not try to decide for your foster children whether their gayness was real or not and cure them of it if you felt it was other than innate.  Love your child for who they are and you'll be fine.Side note:  I don't know where you are located, but in the U.S., the term homosexual has a slightly pejorative connotation (yes, I know it was once the correct term, but so were colored and retarded.  Times change).  Gay or LGBTQ are preferred.
