If you want to tone your PC muscles for increased vaginal lubrication, stronger clitoral sensations, better vaginal grip and greater orgasmic abilities, here's the equipment to get you there. Kegel exercisers are shaped like barbells; insert them into your vagina and flex your PC muscles around them.   Balls also exercise the PC muscles, but you can wear them all day and enjoy sensation from their movement.  Wear them while using your vibrator and intensify your experience.
