PrincessPikachu is right here. It takes some serious time to fill out in all of the right areas. When I was your age I was a stick (literally) and also quite taller than any guys my age (think, beanpole). By the time I was in my late teens I started to fill out in the right areas, don't worry.

hey I am exactly the same I am 21 and i struggle with my hips tummy and legs and no matter what i do i cant see to get any of the weight off.

You are still young, you have all the time to develop physically and emotionally!

I think you've a nice figure and you shouldn't worry about anything.
