A vibrator is a sex toy that is used on the body to produce pleasurable erotic stimulation. Most 2010-era vibrators contain an electric-powered device which pulsates or throbs, which is used to stimulate erogenous zones such as the clitoris, the vulva or vagina, penis, scrotum or anus. There are many different shapes and models of vibrators. Some vibrators designed for women stimulate both the clitoris and the vagina. Some vibrators designed for couples stimulate the genitals of both partners.
