Nero, I've met genetic guys with higher voices than I've ever heard even from women, and they still appear male to me. You're lucky you're treated like a guy; for some reason, unless I'm fully dressed as a guy with binding and whatnot, the majority of people treat me like a chick. I'll never understand it. So I guess it really doesn't matter how high your voice is, or how you dress... it depends on other people. Or something like that.
