OP here. Thanks for the support, everyone - I have told her, and, while she's definitely not into it, at least she doesn't plan to leave me over it. To those of you wondering whether I'm a transvestite, a crossdresser, a transexual, or transgendered - there are waaay too many of these names, and it's confusing. How about I explain it this way: I'm a girl on the inside, and I'm still attracted to girls (a lesbian, perhaps?). I don't mind my body, and I don't mind wearing men's clothes (heck, it's what I grew up with), but I'd like to see what more is out there... I've been hiding it and ignoring it and thinking I'm wrong for a long time, but my control is obviously slipping.
