It doesn't make me uncomfortable actually.
It's like my brain switched from male to female, almost. I feel like "one of the girls" rather then a boy. I apparently start half identifying as a girl, for that period.
I still have my desires and such, and I still consider myself FtM during that period, but I feel like a girl and not a boy for whatever absurd reason. I don't feel like a boy hanging around girls, but like a girl (I guess, maybe not; how would I know what being a girl feels like?). Maybe it's because I'm pre-transition..
