Interesting. I don't think I could deliberately change my gender behavior. I've tried to force myself to walk or act like a girl, by copying others, but within seconds I forget about it and revert.
But I'm not trying to physically transition to male either. I have always had male behaviors, so I'm just myself.
I don't really have a strong female identity.
I sort of think of myself as male, although I have a more female mode.
I was gender fluid most of my life, switching back and forth without being aware of it until I accidentally discovered that a local Thai herb, derris scandens, seems to blend my gender modes and make me an angrogyne, with male leanings.
Strangely, I have always assumed male privilege, even as a child, and anyone who didn't give it to me was going to have a confrontation with me. I regularly fought back, scratched and bit any boys at our small mission school who dared try to bully me. Usually though I ran around with boys and even had my own gang of followers.
After puberty, I began to carry weapons like short sticks to rap strangers who tried to grope me, and of course I had deadly aim with a rock. In college, I took karate and self defense classes for two years.
Even now, if some Thai guy in public transportation does manspreading into my space, I will likely shove his leg, give him a dagger look and make an angry Thai clicking noise. If he resists, I flare up in rage and loudly confront him, sometimes with curses, although I at least try to use a language he doesn't likely know.
