Curved or knobbed vibrators specifically designed to stimulate a woman's G-spot (Gr?fenberg spot). G-Spot vibrators are designed to reach that elusive zone on a woman's interior. Guys will also love what these vibes do for their prostates. Most women use these toys as they would a traditional vibrator. However, the G-Spot vibrator's curved end or knobby middle hits in just the right spot, providing the added pressure that many women enjoy.
