Surprising as it may be to the circumcised men as well as to naturals who have never investigated their own genital sensitivity, the head of the penis is remarkably insensitive. Actually, it is the least sensitive part of the penis. It is even less sensitive than many parts of the skin. It has few cutaneous receptors and has poor resolution for signals of touch. It lacks the receptors of fine touch, and does not feel small changes of temperature. This is easy to be established by self-experimentation and has been scientifically proved repeatedly.[i] Insensitivity of the glans is in conformity with the natural function of the penis.
