Right! I remembered what I forgot about the previous entry. It wasn't a third theory, I'm not sure if there was another one. But I guess I was just gonna say something. I actually don't understand my own theory :\. I guess I don't know enough about genetics, because if there was a homosexual gene, what would it determine? Does the gene actually contain information for a body to naturally release hormones, or whatever happens when somebody feels an attraction to someone, when they see an attractive person of the same gender? Or, does it contain information of exactly which gender to be attracted to? Is homosexuality a single trait, or is lesbianism different from gayness? And then, what about bisexuals? What determines whether one is bisexual or not? Is that yet a different trait? Is it the same trait as homosexuality, but just developed differently? Leave an entry, or at least a comment.
