Have you had Breast enlargement surgery? Some advice from previous experience please?

Hi there, I'm 21 and I have been looking in to getting breast enlargement surgery for a while now. I've got an hour glass figure, and I think I have an alright sized pair but I think if I went up a size or 2 maximum it would fit my figure perfectly. I've contacted MYA and am receiving some info in the post before I go for a consultation. I've always wanted my boobs a bit bigger. Any experiences women can give me please? Or advice?
