My gender identity is very fluid. Looking back on my child hood I realized I moved from stereotypical boy things to stereotypical girl things with ease. That stopped in middle school but that’s another story. The point is I still feel very gender fluid, I sometimes think I could be happy as a slightly feminized eunuch. It would let me present as butch or femme as the mood took me. As for sex, I like giving head and would probably be quite content as a passive sex toy. Ah but there are other times when I want to be the revved up leather bisexual biker chick; fucking men senseless and then leaving the poor saps to go cuddle with my cutie. Hell I need to be a pretty little shape shifter to keep up with my shifting gender identity.
Nature verses Nurture is a debate that should have long sense ended, it is both with environment thrown in for good measure. We are complex and unique creatures who do not fit well into little boxes.
