Much has been written about the so-called Gräfenberg or G spot. According to the literature, it was discovered by Ernst Gräfenberg, a German obstetrician and gynecologist (“It Was There All the While,” April 29, 2002). Years ago, I wondered how was it possible that this erogenous area was discovered only in the middle of the last century. But I still wonder how is it possible that it is still not discovered why the G spot is precisely where it is. To wit, it is there because all primates copulate from behind. In other words, the male is behind and on top of the female during intercourse. The erogenous zones that trigger orgasm are thus at the same spot, as it were, of both the male and the female. In particular, the most sensitive spot of the penis is right above the testicles on the lower part of the shaft, and the most sensitive spot of the vagina is on the interior wall of the vagina just behind the pubic bone. This is where the penis and vagina rub against each other during copulation. Humans have introduced copulation from the front in the last hundred-thousand years, but copulation from behind is still widely practiced among them, too. Of course, copulation from behind goes down the evolutionary tree well past the primates. Now, how is it possible that science is still in the boondocks when it comes to something as basic as the G spot? Human stupidity squared, no less.
