The truth is I think most of us could stand to lose a little weight. (At least in America) But lord knows you'd kill a guy if he told you that he thought you could stand to lose a little weight. Hell, I know that I could stand to lose a little weight. Am I overweight? No. Not at all. However, I know that I could lose 10-20lbs and also still be in a healthy weight range.
I don't need to, nor should I, lose any weight. So, I haven't ever been told by a guy that I could stand to lose a little. Gain a little, maybe. But I still ask my significant other what seems like trick questions. He tells me that if I'm not happy with it, change it. I've yet to kill him for saying that doing a few sit-ups wouldn't kill me.
I ask, though, because I want him to reaffirm his attraction to me. It's blatant compliment fishery, but I like being told I'm pretty. Oh, well.
