Biological reality is that the individual with a 'y' chromosome is a male, regardless of how much he may wish otherwise.  Question--is there a connection between male homosexuality and psychological and/or emotional inability to assume a self-identity and social role associated with being an adult male human?  I'm going to get jumped on for this, but from what research I've seen on the subject (admittedly, not a lot as it's not a subject of great interest to me), there seems to be more evidence pointing to such a connection than evidence pointing to a 'gay' gene.  That of course ain't sayin' much, as there is basically NO empirical evidence supporting the existence of a gay gene.  None.  Those who argue for its existence take it on faith (more likely, wishful thinking).
