How often do girls fap on average?

This subject came up when I was talking with this girl.  I told her like 4 or 5 times a month (I'm serious, I don't really fap that much) but she doesn't believe me as she says even she faps more than that.  Any somewhat credible statistics on how much females fap?

I thought fap = masturbate.

Oh well..  just being plain lazy here..  why type so many letters when 3 will do?
