The "G" in G-Spot is named after the physician Ernst Gräfenberg. The name has stuck, but today we know that the G-Spot is not really a "spot" but rather a broader area inside the clitoris that can be stimulated from inside the vagina.
Meaning: The G-Spot is actually the other side of the clitoris, covered by the anterior vaginal wall and therefore less sensitive than the exposed external clitoris.
Therefore, the G-Spot takes longer to warm up. It becomes larger, more sensitive, and more responsive to stimulation with arousal.
An orgasm from the G-Spot is a truly special and unique experience that requires some time and attention to achieve, but the resulting orgasm is so satisfying and completely different from anything you have experienced before.
