The g-spot is located on the top wall of the vagina just above the pubic bone
. The best route to its discovery is through digital penetration. Have her lie on her back with her knees up. Slide in one or two fingers with your palm up about 2-3 inches deep. Keep your fingers curled as you stroke the area just above the pubic bone. It is best that she is very stimulated at the time, as that causes the g-spot to engorge. If barge right in, that area will be tiny, and your efforts will be pointless. However, once she's warmed up and you tap that g-spot, she will have orgasms like neither of you thought possible.
