i'm 5'6 and 110 pounds. i have a small waist and 32a boobs but my butt and thighs are bigger than the rest of me. not that they're fat but they're not slim like my torso. i know that guys like that though. what i was wondering is since i'm classified as "underweight" should i try and gain weight healthily and hope it goes to my breasts or is that an unlikely possibility? or should i just stay where i am now. my small breasts make me self conscious around guys.
