The whole area is a spongy tissue like spot about the size of a quarter. It feels rougher to the touch than the surrounding tissue. The G-spot is composed of erectile tissue, which means it swells up when blood rushes to it…which is what happens when a woman is aroused. The more aroused she is, the more likely you are to find it and be able to use it!
It is located about one to two inches back from the vaginal opening inside the front vaginal wall. The “front” wall is the wall of the vagina on the same side as the belly button.
(And in case you were wondering where the male G-Spot is…)
