Functions of the Foreskin

The foreskin represents at least a third of the penile skin and increases sexual pleasure by sliding up and down on the shaft

In order to appreciate the sexual functions of the foreskin, refer to Figures 5–9, which clarify what the foreskin is and how it works. Figures 5 and 6 show the difference between a circumcised and an uncircumcised penis in the relaxed or flaccid state. Note that the foreskin serves to cover the glans or head of the penis. Figure 7 shows this diagrammatically. Figure 8 shows the circumcised penis in the erect state. The shaft skin is taut. Figure 9 shows the uncircumcised penis before, during, and after erection. Note that the inner foreskin layer becomes exposed and the entire foreskin moves to loosely cover the penile shaft.

 

 

 

Taylor, Lockwood, and Taylor studied the foreskin tissue at the Department of Pathology, Health Sciences Centre, University of Manitoba, Canada. They reported their results in the British Journal of Urology in an article titled “The Prepuce: Specialized Mucosa of the Penis and Its Loss to Circumcision.” Based on the examination of 22 adult foreskins obtained at autopsy, they found that the outer foreskin’s concentration of nerves is “impressive” and its “sensitivity to light touch and pain are similar to that of the skin of the penis as a whole.” The foreskin inner surface is different. It is mucous membrane similar to the inner surface of the mouth, also rich in nerves and blood vessels. Between the inner and outer layers of the foreskin is a unique structure they call a “ridged band” that contains “specialized nerve endings.” The researchers conclude that the foreskin has several kinds of nerves and “should be considered a structural and functional unit made up of more or less specialized parts. . . . The glans and penile shaft gain excellent if surrogate sensitivity from the prepuce.”

 

 

 

 

 

 

The foreskin represents at least a third of the penile skin. It protects the glans from abrasion and contact with clothes. The foreskin also increases sexual pleasure by sliding up and down on the shaft, stimulating the glans by alternately covering and exposing it. This can occur during masturbation or intercourse. Friction is minimized, and supplementary lubrication is not needed. Without the foreskin, the glans skin, which is normally moist mucous membrane, becomes dry and thickens considerably in response to continued exposure. This change reduces its sensitivity.

“I asked an intact friend to tape back his foreskin, go about his daily business, and report back. He said the experiment only lasted 15 minutes. He couldn’t stand the chafing. He said it was like touching the white of his eye with his finger.”

 

 

 

 

 

In addition, the loss of a secretion called smegma of the inner foreskin layer removes natural lubrication. Oral-genital sexual activity is more common in the United States than in many other societies. Could the lack of natural lubrication of the penis due to circumcision be a reason?
