Circ removes the most sensitive parts of the penis (Ridged band and often it also removes Frenulum).

Furthermore, no longer protected by the foreskin glans develop few more layers of skin in order to protect sensitive nerve endings. This process called keratinization which leads to further sensitivity loss.

Please take a look at a recent sensitivity study published in the BJU International (British Journal of Urology) in April 2007.

This study was the first time that the intact and circumcised penis were thoroughly, systematically and scientifically tested for sensitivity. The testing method was monofilament testing, the same method used in assessing peripheral neuropathy, such as lack of feeling in the feet of diabetics. The resulting measurements of sensitivity are quantifiable and reproducible. The study was submitted for peer review before being approved for publication.

The study's objective: to map the fine-touch pressure thresholds of the adult penis in circumcised and uncircumcised men, and to compare the two populations.

The conclusion, from the abstract: The glans of the circumcised penis is less sensitive to fine touch than the glans of the uncircumcised penis. The transitional region from the external to the internal prepuce is the most sensitive region of the uncircumcised penis and more sensitive than the most sensitive region of the circumcised penis. Circumcision ablates the most sensitive parts of the penis.

3. Moisturizing the glans is another important function of foreskin. Once removed, the skin of glans gets dry which most of the time leads to inability to have sex/masturbation without an artificial lubricant. On the other hand intact men do not need it at all. Foreskin slides up and down the shaft of the penis providing an easy and smooth penetration, lubrication and additional pleasure for both partners.

While this video is for artificial foreskin (and I really have mixed feelings about the product) this video is AWESOME as far as showing the process of keratinization and loss of sensitivity by using computer graphic, explaining the process in a very powerful and easy-to-understand way.
