As for myself, I hate my huge love handles... I mean, I love curves and love handles to some extent, but mine are a bit big... Yeah.
Personally, I think everyone, whether boy or girl, is insecure about their body. Girls try to look pretty, and boys try to look strong and buff. Different standards, but same insecurity. I'm sure you're fine the way you are. Your body is still growing first off, and secondly, no one's body is ever perfect. You'll be fine. There will be plenty of people who will find you attractive when your time comes.
