Girls masturbating

[Supercooldude]

I have some questions for girls...

Ok we all know guys masturbate every day... What I wonder is how common is it for chicks to masturbate, I mean is this something that every girl does or only some? How old are girls when they start masturbating, how often do they do it, do they ejilluate a lot, what do they think about while masturbating, and other things like that is what I'm interested in.
