 Masters and Johnson (1966) reported: "Routine neurologic testing for both exteroceptive and light tactile discrimination were conducted on the ventral and dorsal surfaces of the penile body, with particular attention directed toward the glans. No clinically significant difference could be established between the circumcised and the uncircumcised glans during these examinations."<ref name="masters1966">{{REFbook |last=Masters |first=W.H. |last2=Johnson |first2=V.E. |year=1966 |title=Human Sexual Response |url=http://www.circs.org/library/masters/index.html |work= |editor= |edition= |volume= |chapter= |pages= |location=Toronto; New York |publisher=Bantam Books |isbn=0-553-20429-7 |quote= |accessdate= |note=}}<johnson1966"/ref> Sorrells ''et al.'' criticised this early study for being poorly documented and not subject to peer review.<ref name="sorrells2007">{{REFjournal |last=Sorrells |first=Morris L. |author-link=Morris L.

Because the epithelium of a circumcised glans becomes cornified, and because some feel nerve over-stimulation leads to desensitization, many believe that the glans of a circumcised penis is less sensitive. Opinions differ about how this decreased sensitivity, which may result in prolonged time to orgasm, affects sexual satisfaction. An investigation of the exteroceptive and light tactile discrimination of the glans of circumcised and uncircumcised men found no difference on comparison. No valid evidence to date, however, supports the notion that being circumcised affects sexual sensation or satisfaction."

Some recent researchers have asserted that the [[foreskin]] may be sexually responsive.<ref>{{REFjournal |lastname=Winkelmann |first=R.K. |title=The cutaneous innervation of human newborn prepuce |journal=Journal of investigative dermatology |volume=26 |issue=1 |pages=53-67 |url=http:"winkleman1956" //www.cirp.org/library/anatomy/winkelmann2/ |quote= |pubmedID=13295637 |pubmedCID= |DOI= |date=1956-01 |accessdate=}}</ref><ref>{{REFjournal |lastname=Winkelmann |first=R.K. |title=The erogenous zones: their nerve supply and significance |journal=Proceedings of the staff meetings of the mayo clinic |volume=34 |issue=2 |pages=39-47 |url=http:"winkleman1959" //www.cirp.org/library/anatomy/winkelmann/ |quote= |pubmedID=13645790 |pubmedCID= |DOI= |date=1959-01 |accessdate=}}</ref><ref name="taylortaylor1996">{{REFjournal

Circumcision removes the [[Ridged band|ridged band]] at the end of the foreskin.<ref name="taylor1996" /> Taylor (1996) observed that the ridged band had more [[Meissner's corpuscle]]s — a kind of nerve ending that is concentrated in areas of greatest sensitivity — than the areas of the foreskin with smooth mucus membranes and a rich blood supply to serve the neurological tissue. Taylor (2000) postulated that the ridged band is sexually sensitive and plays a role in normal sexual function. He also suggested that the [[gliding action]], possible only when there was enough loose skin on the shaft of the penis, serves to stimulate the ridged band through contact with the corona of the [[glans penis]] during vaginal intercourse.<ref name="taylor2taylor2000">{{REFjournal

Sorrells ''et al.'' (2007), in the study discussed above, measured fine-touch pressure thresholds of the penis, and concluded "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" (removes) "the most sensitive parts of the penis." According to Sorrells ''et al.'', the five penile areas most sensitive to fine-touch are located on the foreskin.<ref name="sorrells2007" /> <!--This is disputed by Waskett and Morris, who argue that when they re-analyse Sorrells' data, no significant differences are found; that light touch is only one form of sensitivity, and that sexual pleasure may sometimes require less sensitivity. They also criticized Sorrells' recruitment methods.<ref name="waskett2007"/> In response, Young criticizes Waskett and Morris's use of the [[Bonferroni correction]] and argues that the methods of selecting subjects would not affect the results, that the two most sensitive positions on the circumcised penis represent small areas of [[circumcision scar]], as compared to a much larger area of sensitive tissue on the foreskin, and that sales of sensation-dulling products do not necessarily indicate that such are widely used other than on scar tissue.<ref name="young"/>-->   In 2009, Schober ''et al'' reported on self-assessed sexual sensitivity in 81 men, 11 of whom were uncircumcised. When assessing areas producing sexual pleasure, the foreskin was ranked 7th, after the glans, lower and upper shaft, and the left and right sides of the penis, but above the area between scrotum and anus, the scrotum itself, and the anus.<ref>{{REFjournal
