I've noticed this about myself as well.
I've always felt like I didn't feel right in my own skin, wished I could be a woman, and hated society for it's expectations of me for being a man. My voice has always bothered me, and even little things like how I move or what I have to wear vs. what I want to wear and . . . bla bla bla . . . despite all that, I didnt know I was trans until a few years ago, because I'd never had the dots connected, and I thought I was just a freak and needed to keep all that to my self for 32 years.
But ever since three years ago and finding out in an anthropology class that all of that is related to being transgendered . . . I feel like I need to learn more. I need to read more. I need to pay attention to how women act vs how I act. Trying to learn about my rights (...which often quickly becomes learning about my lack of rights) as a transexual, trying to learn about clothing and . . . all of it. Now I'm even trying to find a community, and have even come out to a few friends who I know won't freak out (...though one of them did suddenly assume that I was FtM and had already transitioned and that that explained some of the very small things I do or say at times that they thought betrayed me as a man when in reality it was me slipping up and revealing my true nature and . . . yeah . . . strange conversation having to correct her . . . even still, I was just happy she didn't flip out), and trying to find a therapist.
While I am thinking about it more often and trying to learn more to insure I make informed, intelligent decisions, I have to say the feeling hasn't increased. I've always felt this way, like a freak trying to fake my way through life. And now that I have an answer to not feel that way . . . the need to learn everything I can and to observe and to think has only grown.
In my case I think it's because of the old saying, 'Knowledge is power". If that's the case, I tend to think about all this thinking and research and hard questions I'm asking myself and observations I'm doing . . . is me loading up on knowledge so I can do what is best for me.
