The average would be meaningless...
What's your height? What's your build?
And if you really want to head for "normal" then it would probably be better to head for the Median rather than the Mean (=average); I've not plotted the distribution (not enough 15yr old girls to sample to hand) but my expectation would be that the median would be more representative.
Perhaps the most important question is: are you happy with the way you are? If so, then how you are is probably right for you already.
