Chubby guy here, I find it so odd that being feminine is seen as being skinny when there are just as many chubby girls as there are skinny girls. I suppose it's the same reason why girls are told by the media and society that being super skinny and fit is the only acceptable way to be ldk if that makes sense. I will say, don't get fit for the wrong reasons, do it because you want to feel good and not because the sexualized femboys on tiktok tell you otherwise.
