One specific spot inside my vagina hurts during sex. is that the g spot?

Sexual pleasure/pain: Sexual pleasure is not a common problem once "desire " is mastered. Interested and committed to coitus, the rest is all good--unless, there is something to cause you pain (not normal) or keep you from reaching orgasm (very common). The g spot, deep to the vagina, under the bladder should not cause pain, unless you have a bladder problem. Any other pains are abnormal and need medical attention.
