How many flaws am I allowed to have?

13. None

Thats the whole point isnt it? If you find a flaw kill it before it multiplies.
Women and how we perceive our 'flaws' are big business indeed. And you are right it starts very young, that feeling of constant physical imperfection. Hard to overcome, hard to find one's own way through all that. (There is nothing wrong with the art of self decoration, but it's ever so much more satisfying when it's meaningful in some way)
It can be done though. It's simply not encouraged.
