What's the best sex position for g spot stimulation?

G spot: Manual manipulation is the best way to stimulate the g spot . The best position depends on the person preference (trial and error).

Woman on back: Having the woman lie on her back, legs wide open, knees up, feet flat on the bed near the buttocks or straight up in the air, or on the mans shoulders, hips at the very edge of the bed. Man stands between the woman's legs and thrusts forward. This should help the head of the penis slide into and over the g-spot. Good luck!
