[[William Keith Campbell Morgan| William Keith C. Morgan]], {{MD}} (1965), a Canadian physician practicing in the [[United States]], had a comment critical of the then American practice of non-therapeutic (routine) [[circumcision]] of infants. With regard to sexual function, he identified the ease of penetration and said:<blockquote> Now let us consider whether the operation is in any way harmful or contraindicated. The function of the prepuce is to protect the glans, the latter being almost insensitive to most ordinary tactile and thermal stimuli. It has, however, specific receptors for other pleasurable sensations. Removal of the prepuce exposes the [[glans]] to foreign stimuli which dull these special receptors. 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 vaginal [[mucosa]]. Penetration in the [[circumcised]] man has been compared to thrusting the foot into a sock held open at the top, while, on the other hand, in the intact counterpart it has been likened to slipping the foot into a sock that has been previously rolled up.<ref name="morgan1965">{{REFjournal |last=Morgan |init=WKC |author-link=William Keith Campbell Morgan |title=The rape of the phallus |journal=JAMA |date=1965 |volume=193 |issue= |pages=123-4 |url=http://www.cirp.org/library/general/morgan/ |quote= |pubmedID=14310332 |pubmedCID= |DOI=10.1001/jama.1965.03090030045013 |accessdate=2019-12-21}}</ref></blockquote> Morgan (1967) addressed the issue again 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=Morgan |first=William Keith C. |init=WKC |author-link=William Keith Campbell Morga |etal=No |title=Penile Plunder |trans-title= |language= |journal=Med J Aust |location= |date=1967-05-27 |volume=1 |issue=21 |pages=1102-3 |url=http://www.cirp.org/library/general/morgan2/ |quote= |pubmedID=4226264 |pubmedCID= |DOI= |accessdate=2019-12-21}}</ref> </blockquote> Falliers (1970) commented in a critical letter to the ''Journal of the American Mmedical Association'':<blockquote>The sensory pleasure induced by tactile stimulation of the [[foreskin]] is almost totally lost after its surgical removal. The surface of the exposed [[glans]], as we know, has no capacity to receive and transmit any fine sensations of touch, heat, etc. Consequently, the fundamental biological sexual act becomes, for the [[circumcised]] male, simply a satisfaction of an urge and not the refined sensory experience that it was meant to be.<ref name= "falliers1970">{{REFjournal |last=Falliers |INIT=CJ |author-link= |etal=no |title=Circumcision (letter) |journal=JAMA |location= |date=1970-12-21 |volume=214 |issue=12 |pages=2194 |url=http://www.cirp.org/library/general/falliers1/ |quote= |pubmedID= |pubmedCID= |DOI= |accessdate=2019-12-21}}</ref></blockquote> And so began the investigation of the sexual effects of male [[circumcision]].<!--Only medical trade associations, such as the [[American Academy of Pediatrics]] (AAP), a [[medical trade association]] which represents doctors who profit from carrying out circumcisions, still contend that [[circumcision ]] does not harm sexual function. The American Academy of Pediatrics points to a survey (self-report) finding [[circumcised ]] adult men had less sexual dysfunction and more varied sexual practices, but also noted anecdotal reports that penile sensation and sexual satisfaction are decreased for [[circumcised ]] males.<ref name="AAP1999">{{REFjournal
