Malachite, someone told me that too! I was like 14 years old then, and felt a bit ashamed and 'wrong' for a while, until I was like "Wtf is that for total BS!" and decided just to sit how I like, which is sorta 'big' and spread-legged. It's just more comfortable than being scrunched up in a corner, legs close, arms close, everything close. Really, HOW can women sit comfortably like that? (I think the answer is NOT! Lol)
They DO say that girls shouldn't sit spread-legged (it's 'indecent' (speaking of bs. I have never seen a guy peer THROUGH my pants. Now, THAT would be scary!) and guys shouldn't sit legs-crossed (my dad does that all the time btw, and he is not gay nor an feminine guy. I more often see older guys crossing legs than younger ones tho'. But WHY NOT!? Firstly; you ARE no man, secondly; even if you were, if you prefer sitting like that, SO WHAT!)
