I wanted to say that all those people who identify as nothing who crossdress say they don't fit anything. Well I researched it and there is a term for that and that term is androgynous. One who is male/female display and in spirit or dress or anyway else. That is what they are. Many women are that and use it well. So, on males who cd that is at least what they are. They are not gender variant but are androgynous.
