Can a 4 yr old show signs of homosexuality? I am asking because I caught my son in his bed under the covers with a neaighbor's son. They both had their pants off and erections. ( which is weird to me anyhow cause they are only 4 damnit! haha) I told them to put their pants back on and later pulled my son aside to ask what they were doing in the bed with their pants off. He told me they were kissing butts and putting weewees ( his word for a penis) on butts. Now I know some people say homosexuality is something you are born into and not always a decision. I am just wondering if that is the case then could this be a sign my son may grow up to be homosexual. My friend spanked her son liberally, but I am not threatened by the thought of a gay child as much as she is. I simple explained to my son that he is not supposed to take his clothes off in bed with other children, boys or girls. BTW I am a woman in a straight marriage and he has never been around anyone that I know that is homosexual.
