Milly, I'm sorry that my posts don't seem clear to you.
As I said before, I suggested the idea that gender is a physical reality (sex), that this is reflected in individual embodied experience at a young age (what I called core gender identity) and then overlaid gradually with socially-constructed behaviours and expectations (gender role identity). That's the 'aware of own body' stuff, which I suggested starts to develop prior to (even if it's not, by the time we're adults, easily separable from) the 'pink for girls and blue for boys' type nonsense.
My proposal was that the gender role identity stuff that gets overlaid on the 'aware of own body' can be multiple, conflicting and complex for both men and women. Or in other words, someone could be aware of themselves as female-bodied but have a real love/hate relationship with the roles and norms and expectations that come with that.
This seemed, to me, a more nuanced way of looking at physical (observable) and experiential gender than the statement 'Male and female aren't identities, they are biological realities', which seemed to me to imply that 'male' and 'female' must necessarily be either an identity or a biological reality. My intention was simply to expand on the idea that it might be both, and to suggest some ways that this might be the case.
My personal experience of course doesn't prove anything, but I've gone through periods of feeling very male-identified and simultaneously very conflicted about that, whether on feminist grounds or simple 'this is nonsense, stop it' grounds. I've also gone through periods of feeling very invested in my identity as a woman (including a stint in an all-lesbian commune) but really resenting some of the stuff that seemed to come with being female-bodied. Sometimes I've felt both at the same time, which was a real headfuck. I've never questioned the fact that I'm physically female, but my gender identity has at times felt a lot more conflicted and complicated.
Though I don't expect you to agree with me, I hope I have now clarified what I meant.
