Took me a moment to understand what you were on about, when I think of posture I think more of basic posture as in a person has either good or bad posture
I've always tried to have good posture after learning about it, especially after being involved in a bicycle VS car thing I took to working on and maintaining a good posture on a daily basis
I actually had to learn how to 'act like a man' in younger days and having good posture was a large pat of that
But yes, most men and women tend to stand, walk and generally move differently, I'm lucky in that I've always been perceived as having a rather natural feminine way about me
Naturally I got picked on and made fun of which was bothersome back in the day but now I don't care and if someone comments I just smile and say "Thank you"
