I’ve always sat like that, and I occasionally see men doing it as well, but I remember this one time in like middle school where I was doing it in music class and the 2 kids next to me started talking to me in valley girl fagcent to tease me. I took it as reinforcement to keep at it because I so rarely got to express any real faggotry let alone femininity outside of being the kid who was a brony bc it was a religious school so I couldn’t grow my hair out or anything.
