The
Gräfenberg spot or G-spot is named after German gynecologist Ernst
Gräfenberg. It is a small area in the genital area of women behind the
pubic bone and surrounding the urethra. It is the same as, or part of,
the urethral sponge, the site of Skene's glands.
Stimulation
of the G-spot (through the front wall of the vagina) is said to
promote a more vigorous and satisfying orgasm, and is possibly the
cause of female ejaculation from the Skene's glands, contained in the
urethral sponge. Such stimulation requires a somewhat opposite thrust
to that required to obtain maximal clitoral stimulation via the penis,
called "riding high".
Many sexual advice books encourage couples unable to reach female
orgasm to consider G-spot stimulation as a sexual technique. It is
believed by a growing number of experts that the reason stimulation of
this area causes a "push out" orgasm, even female ejaculation, is that
it has evolved as a trigger point for childbirth. The infant's head
pushes on this precise spot during delivery, seeming to trigger the
final phase of pushing/delivery. This translates, during normal sexual
stimulation, into a more significant contraction of the vagina.
The G-spot may not be just one discrete spot. In fact, some science
writers such as Natalie Angier contend that it is merely the deep
nerves of the clitoris as they pass through the tissue to connect with
the spinal column. The clitoris has deep roots and may in fact change
in size and slightly change in location as hormone levels fluctuate
throughout a woman's life.
A penis that curves upwards has a natural ability to exert more
pressure on the front wall of the vagina. If a penis doesn't curve
upwards, then different sexual positions may be required. For example,
a man whose penis curves downwards may find the doggy style position
is more suitable for stimulating the G-spot as the curve works against
the front wall.
Stimulation of the G-spot through the use of a finger, or fingers, is
possible through the combined pressure of pushing down on the clitoris
while arcing the finger upwards in a beckoning motion. The finger must
be approximately 1-3 inches inside the vagina for this to work.
However, different individuals require different forms of stimulation.
A G-spot sex toy can be used to stimulate the G-spot also.
The stimulation of the G-spot is thought to be more intense for women
beyond their thirties, because of changes in tissue structure inside
the vagina allowing easier access to the G-spot. Some women believe
their thirties are their sexual peak because of this reason.
The term 'G-spot' is also used by analogy as a slang term for the
prostate gland in men, which may be stimulated through anal play or by
pressing on the perineum (skin directly beneath the scrotum).
