You've heard it all before but electric toothbrushes are still the number one pick for me. Slide the handle up in your pussy like a dildo, it's weird but it feels great.
Also in taking my showers I get really wet and sweaty from being, well from being wet and sweaty! haha. I have one of those shower heads that you can take off the wall and massage your body with if you chose, so one day I lay down in the tub and put it on the rougher massage setting and let it hit my clit. Whoah buddy! Your legs start to shake and you start to pop your back and then you have the most AMAZING orgasm ever...ecstacY!
