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.
The erection or the ability to harden in order to penetrate is the trademark of the penis. The glans is the top of the penis and must be insensitive. A glans too responsive could spoil the erection and thwart the penetration. A sensitive glans will interfere with the pleasure sensation produced by the foreskin and will emasculate the sexual act.
That which is rigid is by necessity unfeeling. There is no Hamletian dilemma about whether the glans is sensitive or not and about whether circumcision decreases penile sensitivity or not. Instead there is the inability of those who are pedocircumcised to know this from personal experience.
Circumcised men also know or at least can easily suspect that the foreskin is the most sensitive part of the penis. This is so because they masturbate by toying with the remnants of their foreskins found near the circumcision scar.
The sensation of the glans is far less informative and sensual than that of the foreskin. Circumcision deprives sexual experience from quality, and not merely from quantity. On average when there are no ill side-effects of circumcision, the circumcised men need more stimulation in order to maintain erection or to ejaculate. Some side effects of the operation, however, could change that and even cause premature ejaculation. The pleasure that the circumcised get is not only smaller but different. The sensitivity of the glans additionally declines with time after circumcision as the mucous membrane becomes calloused.
Foreskin is an important tool of foreplay, as revealed by countless testimonies. Foreplay and sexual act of those who lack it tend to be rougher, their climax tends to occur suddenly and they ejaculate immediately after it. The plateau phase[ii] in circumcised males seems shortened in keeping with the length of foreskin.[iii] The good side of this is that they are less consumed by the sexual act. On the other hand they must be less satisfied by it but without knowing it.[iv]
