The G-spot vibrator is a vibrator which focuses on stimulating the G-spot , a small spongy sensitive spot located in the vagina about two inches on the side of the abdomen. What makes G-spot vibrators different from other types of vibrators is that they are usually smaller in size, since the G-spot is located almost immediately behind the vaginal entrance. The top of the vibrator is also curved to provide better access to the G-spot. The round head makes it possible to exert good pressure. The G-spot vibrator can help produce a more powerful and intense orgasm and can also help some women ejaculate.
