If you have any questions about female masturbation this page has the answer. Link is NSFW.

Why do girls masturbate less than boys?

Because it is a biological necessity for males to eliminate the sexual fluids their bodies produce. It is also believed that masturbation keeps a male's sperm in better condition for reproduction. But females only do it because it's fun. So it makes sense that more males masturbate, and that they are more likely to make a daily habit of it. Masturbation has been observed in every species of mammal, but there is no species where the females masturbate more often than the males. There is also no society on earth where the women masturbate more than the men.

I consider this a public service announcement. You are welcome.
