More recent studies have backed up this finding, leading some to call the Skene's glands the female prostate.^[10] This finding has been used to claim that the G-spot is actually a system of glands and ducts that surround the urethra. This system is located within the anterior (front) wall of the vagina, about one centimeter from the surface and one third to one-half the way in from the vaginal opening.^[11]

In July 2002, Emmanuele Jannini of the University of Aquila, Italy discovered PDE5 activity in the area of the G-spot and speculated that the absence of G-spot orgasms is connected to the lack of Skene's glands in some women. In such women, concentrations of PDE5 were much lower.^[12]

However, most researchers feel that the connection between the Skene's Gland and the G-spot is weak.^[2]^[13] The Skene's Gland does not seem to have receptors for touch stimulation and no direct evidence for its involvement has been forthcoming.^[14]

Relation with the urethral sponge

Some claim that the urethral sponge is the same as the G-spot (Gräfenberg spot)^[15], although some say that the two are separate.^{[citation needed]} Some women experience intense pleasure from stimulation of the urethral sponge and others find the sensation irritating. The urethral sponge also surrounds the clitoral nerve, and since the two are so closely interconnected, stimulation of the clitoris may stimulate the nerve endings of the urethral sponge.

The G-spot

The G-spot has always been controversial - some women say it's essential for orgasms while others say it's non-existent. Psychosexual therapist Paula Hall looks at how to find it, what to do with it - and why it doesn't matter if you haven't got one.

If you have one (and I mean if, that's a big if), it's 2.5cm to 5cm (1in to 2in) inside the vagina on the front wall. You should be able to feel it with your finger. If you're not sexually aroused it may be no bigger than a pea; once you're aroused it increases to the size of a 2p piece.

It's actually more a of a zone than a spot. If you want to explore and find out whether you have one, feel for an area that's rough, a bit like a walnut, rather than smooth and silky like the rest of the vaginal wall.

The what spot?

Originally known as the Grafenberg Spot, the G-Spot was named after the gynaecologist Ernst Gräfenberg, who first described it in 1944.
Practitioners of tantric sex have been talking about this 'sacred spot' for over 1,000 years.

What is it?

For many women, it's a highly sensitive, highly erotic area that provides hours of pleasure. For others it's a knobbly bit that, when touched too much, creates an overwhelming sensation of needing a wee. Some women can't feel any sensation at all while others don't seem to have one at all.

There are a number of different theories about what the G-spot or area actually is. One view is that it is an area of prostatic tissue similar to the male prostate. The absence of the Y chromosome in the developing female fetus deposits the cells in a similar location and voila - the G-spot. Complete with a similar type of sensitivity to the male prostate

Another expert agrees with the prostate theory but expands it to say that this is not the only reason for sensitivity. He points to the clitoris and the urethra as other sources of pleasure, both of which can be stimulated via the front wall of the vagina. Therefore there are a number of erogenous zones and we should stop seeking the elusive g-spot and instead rename it the ‘anterior wall erogenous complex’ - catchy!

A further expert who was first responsible for publicising the G-spot has recently discovered another use. In research she has shown that stimulation of the G-spot area can increase pain threshold by up to 47%. If the stimulation is arousing, the pain threshold increases by up to 84% and a massive 107% on orgasm. Her hypothesis is that this sensitive and erogenous area is one of natures natural painkillers for childbirth.

So there you go. Basically, we still don’t know for sure - but the important thing is to find out what you’ve got and what you like.

What to do with it

Once you've established whether you've got one or not, you need to discover whether you have one that gives you pleasure or just feels a bit annoying. Stroking is usually the most enjoyable form of stimulation.

Sexual virtuosos recommend inserting the forefinger to about the second knuckle and making a 'come here' motion towards the front vaginal wall. You'll need to experiment with pressure and length of stroke to find out what feels best for you. It's important that you're sexually aroused first, and also worth noting that many women say sensitivity varies throughout the month.

During stimulation, the first sensation might be the need to go to the loo, possibly because the G-spot is on the front wall so your bladder is being pushed. You can check this out by making sure your bladder's empty first then seeing how it feels. The first couple of times it might be a bit odd, but many women say a little perseverance is more than worth it.

Feeling it during intercourse

Depending on the size and exact location of your G-spot, you may or may not be able to feel stimulation during intercourse. You're most likely to feel something if you have your pelvis raised.

Another popular position is to be on all fours or bending over from a standing position and allowing penetration from behind. You'll need to experiment.

Female ejaculation

Some women say they ejaculate when their G-spot is stimulated. Research has shown that approximately 10 per cent of women expel between 9ml and 900 ml of fluid from the urethra during arousal and orgasm. A group of scientists examined some of this ejaculatory fluid and discovered prostatic enzymes, fuelling the theory that the G-spot is the equivalent of the male prostate.

However, another group of scientists examined the fluid and said it was very similar to urine. Latest thoughts are that the fluid is an altered form of urine that changes in chemical composition due to sexual arousal. The research continues.

A final word on the subject

Remember, we're all unique. You may have a sensitive G-spot or you may not. If you want to explore, do it light-heartedly. Don't turn it into the Holy Grail; there are many, many ways to enjoy your sexuality, and the G-spot is just one of them.

Virtually everyone has heard stories about a magic spot inside a woman that, if properly stimulated, will send her to paroxysms of sexual ecstasy. Known as the G-Spot, this area has been the subject of several books and countless magazine articles. But does it really exist? If so, how do you find it?

The simple answer is yes, the G-Spot does exist, but there's nothing mysterious about it. It's simply an area of increased sensitivity that many women like to have stimulated. Named after Ernst Grafenberg, a German medical doctor who wrote about "an erotic zone located on the anterior wall of the vagina along the course of the urethra that would swell during sexual stimulation," the G-Spot was popularized during the Women's Movement in The G Spot, a best-selling book by Alice K. Ladas, Beverly Whipple and John D. Perry.

The G-Spot is embryonically analogous to the male prostate. In plain English, certain embryonic cells develop one way if the child is female and another way if the baby turns out to be male. In boys, the prostate gland is responsible for the production of fluid that makes up the majority of semen. In girls, the area that would have been the prostate becomes the G-Spot. The reason some medical authorities have said that it doesn't exist is because the G-Spot engorges only with stimulation, making it very hard to locate in autopsy studies, the primary source for new anatomical research.
