x.3.2.2.5 G-spot
In 1950 Grafenberg described an area in the anterior wall of the vagina, in particular where the base of the bladder borders on the vagina that, when stimulated digitally, would have an intensely erotic effect. He claimed that a bean-sized swelling could be felt. This was later named the Grafenberg spot (or G- spot). Others were unable to find such a structure, although there was increased sensitivity at the anterior vaginal wall, along the entire length of the urethra. It was thought that periglandular or para- urethral tissue would explain the swelling. These glands do not drain into the vulva, as was always thought, but into the urethra. This glandular tissue is also seen as the equivalent of the prostate in the man: the human female prostate. Prostatic acid phosphatase is also found in women who ejaculate fluid during orgasm (squirting). The consequence of this in practice is that prostatic acid phosphatase can no longer be considered as proof of penetration in cases of suspected rape.
