I tried masturbating with my hands (I'm a girl) for a year with no success in orgasming. I was too young to buy a vibrator, but I discovered the trick of laying back in the bath tub with your legs spread underneath the faucet, and letting the hot water run.. I was 12. And then I discovered the electric toothbrush a few months later. I didn't realize you were supposed to take the bristle head off, no wonder I'm not that sensitive down there now. my family didn't see me for months. Well, not much anyway. I got off 2-3 times a day, at least. I was obsessed with penetration, and I still had my hymen. I tore it with a 1 inch diameter beush handle. It was not pleasant, but i kept trying anyway. At least my first time having sex was more comfortable. Now, I prefer sex to masturbation (though I always use a vibrator during sex, because I wore out my clit with a freaking toothbrush!) and I only orgasm about 8 times a week (sex and masturbation combined, with multiple orgasms in one session)
