Not in a "Which gender am I?" way but in a, I don't know how to process the information/deal with it sort of way...
I've always felt the same since I was little, and now that I know what that feeling is, I can describe it even more perfectly. I feel about 80% male, and the rest a mix of other/female (sometimes I think more other than female). This is a constant in me.
I always knew what transsexuals were when I was little (no idea from where though? weird?) and I contemplated it once, but got, not horrible, but disapproving reactions once when I was confronted about acting like a boy, and if I would have liked to have been born one. The memory is very fuzzy though and I sometimes ask myself if it was real.
But yeah, occasionally through my life i tried to be extremely girly, but these phases failed completely. I felt fake and even depressed after I admitted to myself a whole year of my life had been wasted. I denied it ever happening...Still do a bit, just to get by. Also tried to be cheerful about my period, like everybody else seemed to be for some reason..., and felt really awful about the whole thin in the end, but i thought, well all girls must feel this is unnatural, it's totally gross.
Eventually this year I discovered the whole trans community and it was amazing. I felt "This is what I am! Finally!" but then all the confusion set in...
While I felt great I also felt sad, I knew people would see me differently, I had been taught to look at trans people strangely (I'm glad I learned better early on), but still, it reminds me how society thinks of us. I'm learning to deal with it a little though. If someone can't be made to understand, they aren't worth it. But that brings in issues with my family. I told my mom and while she was accepting, she thought it was a phase. And my dad, I can never tell, so it's pretty hard that I can't experiment with pronouns/names. There's also the, will I ever get a guy? , but I try to tell myself that hiding what I feel to a guy, will just make me unhappy.
Then my other doubt was the whole, "does gender exist?" thing. I'm a highly scientific person, and it really bothered me, has this happened to anybody? How do you think about gender? I'm trying to wrap my head scientifically around something I know in my heart to be true, it's like my brain is battling things out. For now I'm with the it's both a mental and a social thing. Like if I had been born the same in a world where all gender stereotypes were switched I'd have liked pink instead of blue just because I wished to express how I feel to the world subconsciously. But I also cringe at that thought, since I currently live in this reality.
And then there's also the... why not just be a masculine female... which I ask myself, then cringe, then ask myself when I get confused, and cringe. But I can't stop considering it. And then I remember I'd love to get rid of my breasts...and I get really comfortable with the idea of being a feminine boy and then doubt sets in again and the cycle continues. And other people seem to trigger this by asking me the same question.
