After seeing some of the diagrams on here of the g-spot, etc... I've become suspicious that my wife's strong orgasms aren't g-spot... but as a result of her stimulating her cervix with the vibrator. Last night I pulled the vibrator toward me so that it hit the inside upper wall (her on her back) just inside her -- you know... along that firm 'bone' at the front wall. She experienced intense sensations like she had to pee. I was thinking this was the spot, but after a couple minutes it didn't turn from the pee sensation into anything else so she had me stop. Any ideas? And why didn't it change into sexually pleasing stimulation if it was in fact the g-spot?
