A male lesbian is a physiologically heteosexual male who wishes he'd been born a girl. He feels alienated by the social standards of gender roles. He may be a crossdresser or consider himself transgendered, but he is probably not transsexual. His ideal would be to be able to be his feminine self in a relationship with a biological female. If he is open about this, he may be ridiculed by both the gay and straight communities.
