Congratulations, you're the lucky one among your friends to develop breasts first. Welcome to a few hellish weeks of feeling like an outcast!

The good news is that your friends will soon be in the same boat as you and will also begin replacing their kid bodies mwith adult bodies. Say goodbye to the shell you once knew, because in a few short months, you're going to have a brand-spankin'-new one, with curves and points where previously there was naught.

And don't worry about big or small or "normal." In the confusing-as-hell land of adulthood, there is really no such thing. We come in all shapes over here. But for your age, that size is perfectly normal.

lol thank you!

It's actually not big. I've been a 'B' all school year and I still get made fun of for small boobs. It may just be that you developed faster and they haven't yet. Big is like a D. A and B are just average.

PS
I'm 14 and starting developing when I was 11.

I wouldnt say they are big, its a nice average size, and you are lucky to have developed boobs first before all your friends. And it may feel weird and wrong, but you feel soon get used to your boobs and you will start loving them =D

no their not really that big. im 14 and im in a size C38 thats a little bigger than average for my age but not by much. your probably at the right size for your age.

no. im 14 and im a 34dd, no offence btw
