I live as female at the moment, but I can't imagine being a girl. I should probably explain because that doesn't make much sense; I'm female on all my paperwork and introduce myself by my birthname, and aren't out, but I act, and dress as me, a male. I get read as male by those who don't know me, and I can live like this to some degree of comfort. The thought of trying to present as female and fit in would be impossible though. I just don't think I could ever do it.
As for your hobbies, you're gonna get ribbed whatever you do. whether it's xbox or ps3 you play, whether you prefer COD to halo, or if you play sport or would rather take computers apart. People find anything to tease others about, it's just a fact of life. And in all honesty, how many people will know you knit? No one knows that I read, or take photographs, or spend my nights making things I need, punchbag, harnesses, packers ect.
My mantra is: I'd much rather be hated by others than hated by myself.
