I'm a 32A. My boob size never really bothered me at all until I was about 16. I found it hard to find bras in my size in shops and catalogues; most of them started at a 34B and a few at 32B. If there were any my size, they were stuffed full of padding/gel/air. It was as if they were saying "This is the size you are
meant to be, loser!" and I got all depressed even though my breast size was proportional to the rest of me and it looked fine. In the end I went to a forum about boobs where the members helped me feel better by showing me the advantages of having smaller boobs and showing me that larger breasts come with plenty of disadvantages, too. I also learnt that bras can be bad for the health of your breasts (possible links to cancer) and I ended up ditching the bras that got me so self-conscious in the first place and became a much happier person with a little bit more money to spend on things other than ridiculously expensive bras.
