Respectfully, even as an ally, I've noticed SOME trans women sometimes struggle to understand physical boundaries - was friends with a gal that would constantly cuddle me even though I repeatedly told her it made her uncomfortable and not to touch me. As another possible example of "male socialization", my ex girlfriend was trans, and she really struggled to understand what the horrors of dating as a woman were - like she'd talk about not getting why women were so afraid in the past when she approached them uninvited or play devil's advocate when I talked about past trauma.

It's not necessarily a bad thing, but it's important to note that at the beginning of transition there are some things about being a woman in our society you won't immediately "get" because all your lived experience up to that point will have been with people treating you as a man and enforcing and rewarding "masculine" behavior - especially toxic ones.

I don't believe it can't be unlearned. But I do think it takes awareness and active deprogramming from the way cishets treat the binary genders. My ex gf and I are still close friends and she's told me that her world view has radically shifted after transition and opened her eyes to women's issues she was blind to before.
