When I was younger I was all: You should be happy with who you are! Never change yourself for anyone!
Then I grew up, I had my own insecurities. I still stand by: Don't change yourself for anyone else, but if you want to change yourself for yourself, I think that's fine.
I'm an A cup as well, and I think when I lose weight I'll be an AA - my mum has small breasts, but most of the rest of my family have big boobs - there is still time for me! :P
Anyway, whatI'm taking a long time in saying is, there's nothing wrong with having a boob job to make yourself feel better - discuss it with your partner first though, and make sure it's something you really want to do
Some people may look down on you for it, but those people simply don;t get it. Maybe they never had any major insecurities, and if they did it probably didn't have much to do with their bodies (Unless it was like acne).
Wouldn't it be great if those who want breast reducions could magically remove a cup size of three, and for them to appear on someone who wants bigger boobs?
