Where is the G-spot and what does it do?
There’s a small area called the Grafenberg spot, or G-spot, inside the vagina. It’s located about an inch or so inside the vaginal opening on the upper vaginal wall — closest to the bellybutton. The G-spot is sexually sensitive and swells slightly during arousal and feels raised or bumpy.
Although all women have this tissue, some like their G-spots to be stimulated and others don’t. And many notice no difference in sensation one way or the other. Many women have orgasms, and about 10 percent ejaculate when their G-spots are stimulated.
