I think you're under the mistaken impression that being multiple is somehow wacky or Different. It's not. We're not "people who don't belong, who feel out of place in their own skin, who are too much for themselves". We're just people who happen to share our body with other people.

You don't even seem to have much of a concept of what multiplicity is. It's not a role playing game. We don't "live a thousand different lives." Each one of us in a body is an individual. If one's a virgin, they can't also be a whore. If one's male then he's only a man. He has no clue what it's like to be a woman. If his body is female, he doesn't even have a clue what it's like to be a man in a male body. Nor is multiplicity in anyway comparable to a part of you being jealous. We're not sides of someone's personality.
