Is there a term for this?

Uh.. as far as I know, "androgynous" means "ually ambiguous" so he can't be BOTH androgynous AND heteroual. He can LOOK androgynous but it sounds like he has a definitive ual identity (heteroual). It simply sounds like he's a guy who likes unconventional women. I don't think there's a specific term for this but in this day and age of term propagation, you never know. Have you looked at some psychological/psychiatric sites for this term?
