Allow me to illustrate a faint echo of (2). I once decided to try adopting one of my ex-wife's identifiable stances: standing, feet under the shoulders but one foot angled out with the knee of that leg bent, weight on the other leg with that hip pushed out, and hands on hips. You've seen lots of females take that stance, and few males; it's a stereotype. When I did that, I had the strangest feeling come over me, like something was just wrong. It was a unique experience.
Just to support that, I did that and it felt natural. Admittedly, I did have a back injury, and I was basically using those hands on those hips to support my spine. But just to show, it's not gender related, a biological male can do it naturally too. Makes me feel even less convinced that there is any particular thing that makes a case that a man is somehow living as a woman, or vice-versa.
(And for that matter makes me more convinced that body language theory holds more water than phrenology or graphology. Hands on hips meaning "I stand my ground" or such? Bleep off, I used it myself for a whole other reason. Lack of eye contact meaning dishonesty? Yeah, well, as a diagnosed autistic, I can tell you it can mean autism instead. Sweating meaning you hide something? Yeah, not always, based on your thyroid and usual environment, your body temperature can be different enough. My thyroid is broken in the opposite direction, but yea, it influences your preferred temperature and stuff. Etc.)
Edit: just to further that point, minus the hands on hips, it's actually the "at ease" position for the Russian army, and at least was for most of the Warsaw pact armies. Literally it was: looking straight ahead, stand straight,
heels together, shoulders back, arms straight down the sides touching the trousers, fingers curled to a loose fist, chin up,
right leg straight,
left leg slightly bent and relaxed. (Might have been hands behind back for some of the Warsaw pact countries. Other than the USSR, of course.) So yeah, one of the two major blocs in the cold war didn't think it was girly or anything
