The Grafenberg-spot (G-spot) is an area in the vagina that is very sensitive to stimulation.
·        The area is as big as an euro and to be found in the front wall of the vagina, in between the opening and the cervix. It’s one-third to one-half way in from the vaginal opening.
·        It’s a ring of spongy erectile tissue surrounding the urethra.
·        If you stimulate this area you can get the feeling you have to pee. This feeling subsides after a few seconds.
·        Some girls get excited when they stimulate their G-spot and can even come this way, while others feel nothing special: everyone is different.
