It's kind of a term for people who aren't quite comfortable with their assigned gender (either in how they want to be perceived, or how they self-identify, or whatever), but don't identify as the other traditional gender. It means a variety of different things, including women who like to be seen as men, as well as people who see themselves as neither men nor women, and a bunch of other stuff too. It's an optional label like any, but I just thought there are SOME genderqueer women who describe themselves a bit like you, so you might find you have something in common. I suppose it partly depends on WHY you want to pass as a guy part of the time. Is it just for fun, or is it an expression of your identity, or... So it makes me think of the androgyn boards here. Maybe it's not appropriate for you I dunno, but you can try. What I do know is that the assumption is a crossdresser is going to be a bloke in a dress, so no female crossdressers here. I certainly don't come into this section generally, even though I do crossdress to a degree.
