By "masculine men" if you mean "ultra macho" this is a stereotype. Most guys are, well, just guys. They don't dress as girls but this does not make them any more masculine than a CDer who is presenting in guy mode.
That said, I love my SO for all of who my SO is, no matter how my SO presents. I am ultra accepting and supportive but this does not mean that I have a general preference for CDers or Gender Non-Conforming people.
