In fact, this isn't even hinting. This is shoving it in her face.
So, my friend who moved to Japan has been talking to me lately on AIM and we're really close and what not. Whenever I get depressed like I have been recently, she asks why, and I tell her that it's because of gender issues. I've told her about my phantom penis, about how I don't like anything about being a girl, how I bind to make my chest smaller, I joke about being a guy all of the time and she's even joked about me being her "other boyfriend".
Once, I told her that I'm an "it", not seriously, of course - this was before I felt like one gender. I felt like either or neither, you know?
I told her I was getting a therapist because I've been having gender depression and I can't handle it anymore. I've even told her I have gender dysphoria.
And yet, she still thinks of me as a girl and such. She does call me her "man whore" (a guy who is a whore - I'm still a virgin, btw) though, so I guess that's something.

I mean, I've practically TOLD her. It's not even a hint anymore. It's more like a "HEY. I'M A DUDE." in-your-face hint.
