How to feel ok with your body?

I'm sure many girls have my same problem. I'm 16 and hereditary hourgl, that means I'm pretty wide. I'm ok with my weight, I could just loose max 4 kg..I like my body, it's very feminine and all, but I can't seem to relax about it, I keep thinking that I'm fat and that no guy will ever look at me. What do you think about it? What should I do?
