PS. The fact that you think one of your alters is a gay man, but you came out as a lesbian, sounds like a piece of you still might be attracted to men, but you disassociated it for some reason. There might be some trauma in your life where a man hurt you or something? Unconsciously you decided you were done with men and repressed any feelings you have for them, thus creating a personality that express these feelings. At least that's a theory. I might be completely wrong.
