You may have one, or you may not. If you do, you may not feel anything in particular, or you may swoon with delight, or you may simply have a pressing need to urinate. The Gräfenberg Spot, or G-Spot as it is more commonly known, remains a thing of mystery. Look in any anatomy textbook - you won't find it. Ask a surgeon - they've never seen it. Ask a woman, well that's a different story.
Assuming you have a G-Spot, and not all women do, you will find it about one or two inches inside the vagina, on the frontal aspect of the vaginal wall. It's actually better to think of it as an area rather than a spot and this is because it can change in size. When sexually aroused, the area can easily quadruple in size from the initial pea-sized zone. To the touch, the area is a little rougher than the surrounding vaginal wall.
The first authoritative claim to an erogenous zone within the vagina, came in 1944, from the German doctor, Ernst Gräfenberg. Stimulating the area, Gräfenberg wrote, causes intense sexual pleasure and orgasm. Perhaps he was ahead of his time, but for reasons unknown, his ‘discovery' was pretty well ignored for another 30 years or so.
In 2008, doctors at the University of L'Aquila in Italy, confirmed the existence of the G-Spot through the use of ultrasound scans. "For the first time, it is possible to determine by a simple, rapid and inexpensive method if a woman has a G-Spot or not," Dr. Emmanuele Jannini told New Scientist magazine. "Women without any visible evidence of a G-Spot cannot have a vaginal orgasm," he declared.
Case closed? Not likely. The announcement was met with a range of reactions. Some welcomed the news, others were more reserved. Some asked, have you really found a structure in its own right, or is it an internal extension of the clitoris? Others complained that the sample size was far too small to draw such a broad conclusion. Another strand in the argument said the structure was no more than a thickening of tissue that occurs in the absence of the prostate gland in women.
Assuming you think you have the G-Spot, this is good news, right? Not so fast. To begin with, you may be one of the women who have an insensitive G-Spot, so not much joy to be had. If stimulated, it may simply make you feel a bit uncomfortable or simply make you want to pee. Some say this is a good sign and it's worth persevering. Others say they are pretty sure they have a G-Spot but it still isn't as good as clitoral stimulation. Yet others appear to hate having the area stimulated despite the fact they are open to other forms of sexual experimentation.
Human anatomy is such that the missionary position is unlikely to stimulate the G-Spot. Because of its location the penis can only stimulate the G-Spot if positions are adopted that allow the penis to rub against the frontal wall of the vagina.
If there is a message to take from this it is probably along the lines of everyone is different and so is their experience of sexual pleasure. The G-Spot is, perhaps, an erogenous zone, but there are very many others waiting to be explored.
