I found learning about fa’afafine was helpful to show where gender identities from my (Anglo) background did not adequately describe a material situation that is uncontroversial in its own cuktire.

I think that, near universally, we do not. I don't feel my gender; there is no frame of reference against which I could possibly correlate my subjective and entirely internal mental experience against some normative model of what it "feels" like to either be male or female, much less your tautological definition of "man" or "woman".
If you live in a society, you are surrounded by archetypes and roles and norms of gender - or of the performance of gender - which might be a helpful way to think about this post. Things like what clothing and grooming is appropriate are easy examples - and depending on where you are in the world, those standards may be radically different - in some cultures men are expected to adorn themselves to be attractive to partners, in some it’s women. But it’s also what emotions it’s appropriate to display, what kind of authority is afforded to a person, what physical strength and which ailments are reasonable, what kinds of body hair is attractive. We have words that describe a favourable performance of those gender roles (womanly, manly) and unfavourable words (effeminate, mannish). They are enforced, or at least patrolled, in all kinds of ways. Easy example is the kind of differential permissiveness around alcoholism. Why is that? If we have a social or a moral standard, why is it gendered?
You have without a doubt experienced this in your life - and if you’re lucky it’s been internal and not at the hands of the local bully. If you’ve ever checked or modified your demeanour or your outfit or your tone because you are aware that it is too girly or too butch or too macho or too slutty, then that is the sensation of being trained back towards the model.
Of course we do. It’s how we establish shared meaning about what it means to feel any of those things.
The rest of your post describes gender roles; as in, social standards and stereotypes of behaviors attached to sex.
We don’t use the words “woman” and “man” to denote roles or a social subculture, and we’ve never segregated bathrooms, or established segregated sports programs, on the basis of gender roles.
How I feel internally, even if you could correlate it to some objective definition of “feeling female” — which you cannot — does not change that I am a man; an adult human male.
It's not that complicated a concept. Even kids can understand it quite well and there's plenty of information available when you decide that you want to actually learn instead of trying to debate your way into confirming your own opinions.

Children will also readily believe in Santa Claus and the Easter Bunny if their parents tell them that they exist. That's not an argument.
Your assertions are prima facie undecidable, and it's not merely that you're unwilling to defend them — you cannot defend them.
But seeing as you had to trot out the generic, condescending 'go educate yourself', I'll just assume you simply don't know.
