According to Planned Parenthood, the g-spot is located "about an inch or so inside the vaginal opening on the upper vaginal wall — closest to the belly button." And though it may be hard to find, experts suggest doing the "come hither" motion with your fingers as the most efficient way to stimulate the sponge-like surface. Although this type of orgasm can stir up quite a bit of controversy, since many believe that it doesn't exist, if it is an orgasm your body can experience, it is described as one of the best full-body sensations.
