Vibrators come in different styles because people like to use them in different ways. For example, a clitoral vibrator is designed to stimulate the clitoris while a G-Spot vibrator is designed to stimulate the G-Spot. There are many different styles to choose from and some vibrators even combine two or more different styles, for example the Jack Rabbit stimulates the clitoris with the "bunny" while stimulating the G-Spot with the twisting shaft and the outer-vaginal area with the spinning beads. It is best to choose a style that responds to your body, creating stimulation.
