There are many possible hormonal modes and they are expressed dynamically, not deterministically, even within the same body. Hormonal behavior can be learned, it's not purely deterministic. People can be trained to habitually perform certain kinds of behaviors and postures that may not feel natural, and can grow into them, just as people can be trained, pressured, shamed: to carry certain attitudes or use certain language, to eat certain foods, to exercise certain muscles... but not others.

Nature and nurture are not clearly separable as biological and social reductionists like to think. They intermingle in countless ways on multiple scales. People exist on many spectrums, and are dynamic, not predetermined.

I find it hard to make such a clean cut.

Even within these sociological aspects, how much is nature? What is nurture?

So far, I remain unconvinced by any “blank slate” theory to explain gender expression (or anything else for that matter).
