Expanding his waist line, mostly. Like, I know that I have gone in great lengths on how I dislike how every femboy/feminine men has disproportionate hip to waist ratio in CoC2 and how overly shapely their butts are (not for me but I understand there is appeal). I can get past most of them since most of them are not my types (though I do likethe minotaur prince despite of it).you want him to have more meat on him?
Nyze bothers just because he feels the closest to, well, bishonen femboy. Pretty enough to pass for a women but handsome enough to rock a suite if he feels like it. At least he would be if did not take the concept of hourglass figure to utmost extreme out of need to make him look more "girly".
