Anatomical investigations have identified the prepuce as a primary erogenous zone in humans.<ref name="ErogenousZones">{{WinkelmannRK 1959}}</ref> Morgan (1967) addressed the issue in the ''Medical Journal of Australia'':<blockquote>The subcutaneous tissue of the [[glans]] is provided with special sensory receptors that are concerned with appreciating the pleasurable sensations that occur during coitus. They are stimulated normally only when the glans is exposed. In the [[circumcised]] subject these receptors are constantly stimulated and lose their sensitivity. During the act of coitus, the [[uncircumcised]] phallus penetrates smoothly and without friction, the prepuce gradually retracting as the organ advances. In contrast, when the [[circumcised]] organ is introduced during coitus, friction develops between the glans and the vaginal [[mucosa]].<ref name="morgan1967">{{REFjournal |last=WinkelmannMorgan |first=William Keith C. |init=RKWKC |author-link=William Keith Campbell Morgan |etal=No |title="The Erogenous ZonesPenile Plunder |trans-title= |language= |journal=Med J Aust |location= |date=1967-05-27 |volume=1 |issue=21 |pages=1102-3 |url=http: Their nerve supply and significance"//www.cirp.org/library/general/morgan2/ |quote= |pubmedID=4226264 |pubmedCID= |DOI= |journalaccessdate=Proceedings of 2024-08-18}}</ref> </blockquote> Falliers (1970) commented on the staff meetings "sensory pleasure induced by tactile stimulation of the Mayo Clinicforeskin."<ref name="falliers1970">{{REFjournal |last=Falliers |first= |init=CJ |author-link= |etal=no |title=Circumcision |trans-title= |language= |journal=JAMA |location= |date=1970-12 |volume=34214 |issue=212 |article= |page=2194 |pages=39-47 |url=http://www.cirp.org/library/anatomygeneral/winkelmannfalliers1/ |archived=

== Nerve types ==
The two primary sensory receptors in primate [[skin ]] are free nerve endings and encapsulated or corpuscular receptors. While free nerve endings (pain, itch, and temperature receptors) are found in most [[skin]], the encapsulated receptors are concentrated in regions that require specialised touch sensitivity, such as at the fingertips, lips, external genitalia, perianal [[skin]], and transition areas between [[skin ]] and [[Mucosa| mucous membranes]].<ref>{{REFbook

Consequently, this has been studied in detail by respected anatomists for over a century, who have transformed their knowledge by detailed empirical observation of the nerves that are present in the [[foreskin]].
As the most richly innervated part of the [[penis]], the [[foreskin ]] has the largest number of nerve receptors, as well as the greatest variety of nerve receptors. <ref name="garcía-mesa2021"/> These specialized nerve endings include:
* [[Meissner's corpuscles]],<ref name="garcía-mesa2021"/><ref name="Mucosa">{{TaylorJR LockwoodAP TaylorAJ 1996}}</ref>
* free nerve endings, end bulbs of Krause,<ref name="Nervenendigungen"/><ref name="Depth">{{REFjournal
* and Vater-Pacinian corpuscles.<ref name="CutaneousInnervation"/>
These remarkable organs provide the [[foreskin ]] with its amazing ability to detect the slightest sensations of touch, motion, temperature, and pressure. We are still unaware of all the facts about these fascinating structures. Future research may discover even more nerve receptors in the foreskin and help clarify what purposes they serve.The primary zones of erogenous sensitivity are the [[frenulum]], [[ridged band]] of [[Preputial mucosa|mucosa]], and the preputial orifice and the external fold of the [[foreskin]]. All of these zones are orgasmic triggers. Continuous gentle stimulation of any one of these areas can elicit pleasure, [[erection]], orgasm, and ejaculation. Some men report that simple retraction of their foreskin causes [[erection]].

In a 2007 study, which was published in ''BJU International''. They physically measured the sensitivity of all the parts of the [[penis]]. They used a very accurate pressure sensing probe while the test subject, who’s view was blocked with a screen, reported a sensation of touch. To demonstrate precision they took each measurement multiple times. To no surprise, their results corroborated with the neuro-anatomy that has been discussed previously.
"Five locations on the [[uncircumcisedforeskinned]] [[penis ]] that are routinely removed at [[circumcision ]] were more sensitive than the most sensitive location on the circumcised penis[...] The [[glans ]] in the [[circumcised ]] male is less sensitive to fine-touch pressure than the glans of the [[uncircumcised]] male[...]The most sensitive location on the circumcised penis is the [[circumcision scar ]] on the ventral surface [...] When compared to the most sensitive area of the [[circumcised ]] [[penis]], several locations on the [[uncircumcised]] penis that are missing from the [[circumcised ]] [[penis ]] were significantly more sensitive."<ref name="FineTouchPressure"/>

== AAP brushes off findings as inconclusive discards its former Circumcision Policy Statement ==
In the [[AAP]]'s 2012 Circumcision Task force report, the issues of sensitivity reduction were given obligatory mention but largely glossed over, and little space was devoted to the topic. The 2012 Task Force Report received [[American_Academy_of_Pediatrics#Criticism| overwhelmingly heavy critical comment]]. The purpose of the disastrous, now expired AAP 2012 report was to encourage neonatal non-therapeutic [[circumcision]] and [[third-party payment]] so little or nothing was said about the multiple functions of the [[foreskin]]. <ref name="hill2013">{{REFdocument |title=Commentary on American Academy of Pediatrics 2012 Circumcision Policy Statement |url=https://www.doctorsopposingcircumcision.org/wp-content/uploads/2016/08/commentary-on-american-academy-of-pediatrics-2012-circumcision-policy-statement.pdf |contribution= |last=Hill |first=George |publisher=[[Doctors Opposing Circumcision (D.O.C.)]] |format=PDF |date=2013-04-01 |accessdate=2022-04-02}}</ref> The failed 2012 AAP Circumcision Policy expired in 2017 and has not been re-affirmed or re-validated in any way. The AAP currently has ''no '' circumcision policyand does ''not'' recommend [[circumcision]] of boys.
==Sorrells study of penis fine-touch sensation.==
At right is an easy-to-understand illustration of the Sorrells study<ref name="FineTouchPressure" /> showing the loss of tissues. Tissues show in color their relative sensitivity thresholds to light touch. sensitive tissue. On the infographic's opposite side: The AAP's expressed skepticism (quotes from their now expired 2012 Circumcision task force report) on whether loss of all that erogenous tissue could really affect sexual enjoyment.
Arguably, claiming there's no evidence that circumcision diminishes sexual enjoyment is essentially implying the obverse: that it's perfectly safe and reasonable to assume that the human foreskin, despite evolving over millions of years, has no anatomical significance in sexual mechanics, and has zero relevance to sexual pleasure and satisfaction. That statement sounds immediately absurd, however.
García-Mesa et al. (2021) reported: "[s]timulation of genital
Meissner's corpuscles gives rise to sexual sensations."<ref name="garcía-mesa2021" />
==The circumcised penis==
The nerves and other structures mentioned in this article are largely missing on the [[circumcised]] [[penis]].
[[Intact]] men who elect to be [[circumcised]] frequently report very substantial loss of sensation after [[Adolescent and adult circumcision| circumcision]].
