Well, in this case, OP is wearing a skirt, so leaving your legs open while sitting means also exposing your underwear to whomever is sitting in front of you. Obviously it matters less if you’re wearing pants.
As far as gendered body language, it usually comes down to how you cross your legs. Depending on what you have between those legs, certain crossing positions can… squish things.
Since women are more likely to not have anything to squish and more likely to wear a skirt, they are conditioned to cross their legs more often. Men are more likely to not need to care about these things and are free to “man-spread”. This creates the gendered body language stereotype.







“Attention seeking”
Ah yes, the classic inner toxic parent.
