Now relax: some more recent studies suggest that we might not be such sexually obsessed freaks. The genitalia of their improved homunculus are enlarged and normalized. The importance of penis becomes comparable to that felt by non-specialists.
We are not aware whether penile sensitivity of natural and circumcised men has ever been directly compared in a scientific experiment. In some countries where circumcision is wide-spread such investigations are considered unethical. Notwithstanding, British urologists have found that the sensitivity of foreskin exceeds that of all of the fingers.[iv] Yet ordinary natural men without being scientists need not be persuaded that the greater part of the penile sensitivity comes from the foreskin. Often they compare the sensitivity of the foreskin to that of the lips. For that reason perhaps circumcision is not especially fashionable among native residents of France.

Actually, the same must be the motivations for the frequent omission of the existence of foreskin in different sources including medical textbooks. [v]
Our general conclusion is that the cortical sensory area of the genitalia including the foreskin is much larger than currently estimated and spreads toward the cerebral base. The genital areas of the somatosensory cortex in the authentically sexually emancipated cortical homunculus must reach the emotional core of the brain (coloured in red on the picture). Of course, the same considerations are especially valid for the prepuce as it holds about three thirds of the penile sensitivity. Therefore, circumcisions must deeply alter the brain, perception and conciousness. And this has been scientifically confirmed.[vi]
An authentic representation of the foreskin’s cutaneous sensitivity should increase the size of the penis of the sexually emancipated sensory homunculus by at least two thirds. The actual uncircumcised sensory homunculus could be a grotesque tripod figure that props on his foreskin or her clitoral hood. The immense role of the foreskin in human history confirms this.
The foreskin contains about 75% of its cutaneous receptors of the penis. Therefore, the foreskin of a natural homunculus must be so large that it could not be retracted to such a position so as to uncover the glans. We can suppose that either the researchers that normalized the size of homunculus’ genitalia or their subjects or all of them were circumcised. If not they must have refrained from tickling their foreskin for some reason.
