The G-spot is an area 1 to 1.5 inches across and located about two finger joints deep into the vaginal entrance. Its sensitivity to stimulation was first discovered by Ernest GrŠaefenberg (1881-1957 - the G-spot is named after him) in 1950. As a result of direct stimulation the spot, which works like a sponge, will fill itself with fluid. To date it's unknown specifically what these fluids are, from where exactly they originate or what their exact function is. However, they're neither urine nor vaginal fluids and have no lubricating effect. A G-spot orgasm, combined with ejaculation, is much like the male orgasm, including the physical fatigue and the need for a refractory period. The ejaculate will come out in different flows - different women have different numbers of flows and the amount of ejaculate is very individually determined. Science has different opinions on the question if all women have a G-spot and if all are able to ejaculate.
