Kegel balls are sex toys that go by many names: Ben Wa alls, Burmese balls, Benoit balls and Geisha balls. By whatever name you call them, they're designed to work your kegel muscles and provide marvelous sexual stimulation at the same time. Many of them are hollow, such as bells, clappers, or chimes, but there are many solid kegel exercisers to accommodate people with more well-developed muscles. These toys are great for completely hands-free stimulation, since they only require that you move around to do their magic. You could, of course, just use them to strengthen your kegels to improve regular sexual intercourse, but isn't it great that you can get yourself off in the process?
