Please maintain your good health for your own sake, not some fickle man. Any man who would prefer a "size 0" woman with rotten teeth only because she's a size 0 has rocks in his head. By the way, size 0 is vanity sizing; everyone claimed to be size 5 when I was young. I thought I was enormous, elephantine and lots of girls were ready to agree with me; they were also happy to tell me I wasn't pretty because my hair wasn't bleached blonde and I wasn't wearing a lot of makeup. I look at old photos and see now that I was normal weight. Many guys don't have a clue what size their girlfriends really are; they just parrot what their girlfriends tell them. And the number of young men who don't think their girlfriends wear makeup or that beautiful girls in magazine ads or pictures look so "natural" (when they aren't by a long shot) means this to me: you are as beautiful as you think you are; I still get looks and I'm getting close to retirement age. Courage!
