I've always just felt, hmm, I guess you can call it "socially androgynous."
While growing up I was very uncomfortable with the expectations of the male gender role. Still, I didn't drop the toy trucks and run for the Barbies. I preferred Legos and crayons.
"Gender" can refer to biology or it can refer to social roles. Personally, I think that while male and female personalities probably have some natural genetic differences, our culture tends to exaggerate those differences to bizarre proportions.
While I'm not interested in fulfilling the "male" cultural role, I don't necessarily feel I need to be female either. Instead of rejecting "maleness" I'd rather just redefine it on my own terms.
