G-Spot
From Voyeurweb's Wiki about Sex
The G-Spot or Gräfenberg spot, is a small area inside the pussy of women behind the pubic bone. When this spot is touched or rubbed, there is a sensation or urge to pee, but if the stroking is continued during sexual arousal it can be sexually pleasurable. It can be (but does not need to be) a primary source of stimulation leading to orgasm during intercourse in sex positions where the penis can stimulate the G-Spot.
