Yep
And thats why a metrosexual is transgender because by using hair product and getting facials and manicures those things are seen as crossing sex-segregated norms. And a camp gay person by behaving effeminantly or a butch lesbian with their traits associated with masculinity are all also transgender. Also a person who is androgynous in appearance is also transgender.
Certainly for many of these things it has nothing to do with feelling female on the inside but more to do with what our current culture sets aside for male or for female.
But because of the common discriminations, legal issues etc there are strong shared issues and connections that make them all as much a part of transgender as the strongly transexual that know they are in the wrong body from the age of 3.
