Should I Worry About Genderfail?

I manipulated a spreadsheet to provide some data about (most of) my stories, including all sold and/or published. I studied characters first, namely the protagonists. Of 69 stories examined, this bit was eye-opening:

58 male protagonists
6 neutral gender (mostly flash fiction or non-human protagonists)
5 female

Ouch.

I then broke these categories down by age of the protagonists:

58 males = 30 adult, 18 teens, 5 children, 4 older (65+)
6 neutral = 2 adult, 1 child, 3 age N/A
5 female = 3 adult, 1 child,
