This quote alludes the desensitization of the glans in absence of the protection of the foreskin.
"It has been urged as an argument against the universal adoption of circumcision that the removal of the protective covering of the glans tends to dull the sensitivity of that exquisitly sensitive structure and thereby diminishes sexual appetite and the pleasurable effects of coitus. Granted that this be true, my answer is that, whatever may have been the case in days gone by, sensuality in our time needs neither whip nor spur, but would be all the better for a little more judicious use of curb and bearing-rein."
