I feel as if i have the body of a boy?

Exercise, eat a good diet, and you may just have a naturally less curvy body due to genetics. Don't feel bad about yourself though. You're beautiful, and I know plenty of people who prefer bodies that way. That body type usually looks better in clothes with more frills/designs, etc, so try those if you don't already wear them. I swear, you are beautiful just the way you are (:
