The basic vibrator offers a kind of sexual stimulation that is unlike any human touch -- and for many people a vibrator is a great addition to sex play. A vibrator also may be the first and easiest way for a woman who has never had an orgasm to learn to orgasm. How a vibrator feels and what it does will depend on many things, including the power source, material, size and shape. How long a vibrator lasts depends mostly on the quality of the motor and the outer material. Vibrators can cost from $5 to well over $1,000, and the selection can be a bit daunting. Below you’ll find a visual introduction to the vibrator and its many forms.
