I've never quite understood what a "coming of age story" is, for male or female. Certainly in some cultures there is an activity or ceremony or whatever that marks the transition from child to adult, at least within a particular context (that is, America Jewish kids who are bar or bat mitzvah don't suddenly become able to buy alcohol, sign legal contracts, and so on). ISTM, therefore, that all a coming of age story is in contemporary American, and probably most of Western, culture is a story about the event that that particular writer thinks marks the most significant part of becoming an adult.
