Defining the "Grafenberg spot" or "G spot" is not a simple task. Most would simply say it is an area of high sensitivity located within the paraurethral structures. The problem with this definition is, the sensitivity of this area is not likely to be constant. If a woman is not sexually aroused, she may not have a G spot. If the same woman is highly aroused and her paraurethral glands are engorged with prostatic fluid, she may have a very distinct G spot. There are perhaps women who are not aware of a G spot even though they ejaculate and experience a more intense orgasm if their paraurethral glands are stimulated. It is for these reasons that it is important for people not to form a concrete definition of what a G spot is. Each woman will create her own definition, one valid only for her.

The next question for debate concerns whether or not "all" women have a G spot or G crest. This is not really a valid question. The G spot indicates the "sensitivity" of a non-specific area of tissue. The "G-Crest" defines the swollen "condition" of the paraurethral glands during sexual arousal. There are no anatomical structures with these names. This is in part why people have trouble finding it. What one needs to look for are the paraurethral glands. All women have these and it is likely that they all produce at least a small amount of fluid that may seep out and mix with the other fluids that are present in much larger quantities.
