LOL! Not everyone has that issue some go back to the same size. It just so happens the women in my family get bigger and never go back.
That sounds scary. Not that I have a problem with big boobs right now, but I don't really want to get big boobs in the future, either. Am quite happy to be able to run and to move around without loose bits bouncing about. I'd like it to stay that way. But then it's not like we want four or five kids.
