I'm fine with the idea that gender identity is on a spectrum -- or rather two. There is a full spectrum of behaviours and inner personalities for males, from stereotypically feminine to masculine, and equally, a full spectrum for females. Huge overlap, but noticeable clustering around two broad peaks. The influence of personal experience, hormones, background reading, fist size, culture etc will affect where each individual lies on that spectrum, I'm sure.
It just doesn't affect your actual sex. How could it?
