From Sexual Myths About Women:
Myth: Girls/Women don't engage in autoeroticism
Au contrare, mon frère--
Female homo sapiens do indeed engage in autoeroticism (masturbation to the layman). Why else would there be sooo many vibrators in existence? I know, a man may like using one near his anus, but this is rather rare (or at least un- or under-reported).
4Q. How many men/women masturbate?
The best studies of this subject are now quite old. They found approximately 95% of men and about 60% of women claim to have masturbated. There is reason to think the figures for women would be higher if another comprehensive study were done today.

Show me a woman who doesn't, and she is either repressed, ridicuously religious, or a liar. (This is a highly subjective statment, but I refuse to retract it. As for the religious statement, I was raised Catholic, which teaches that masturbation is a mortal sin. This worried me for about three seconds.)
Truth be told, I've been masturbating since I was born; been climaxing since I was thirteen. This is perfectly normal.
She-bop a-go-go! Viva la main!
