I am very insecure about my weight. I weigh 137lbs and I am 5'7". I am a hardcore volleyball player and have a lot of muscle but I'm not totally skinny. Thing is, I don't know if I'm fat or not. I wear a bikini but I feel extremely insecure. I wear pant size 5 or 7. I'm blond and kinda clumsy but I can't help that. How can I feel more confident?
At 5'7", your ideal weight range is 127-159 pounds so you're fine. Especially, if you're an athlete as you will probably have very toned legs. Remember that personality matters more than weight so have an awesome one!
Doesn't really sound bad, but I couldn't really say for sure. I, like most guys, don't really understand how girls sizes work, but 5 doesn't seem very big. And if you're muscular, being bigger wouldn't really matter. Fat is a turnoff, most guys are fine with muscle. As long as you look good, I wouldn't worry overmuch.
