where exactly is the g spot?
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.
