There were, however, some other little noticed papers overlooked by Masters & Johnson, that told a different story. Winklemann (1956) investigated the innervation of the prepuce and found it to be highly innervated.<ref name="winkleman1956">{{REFjournal

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

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

Results of studies of the effect on penile sensitivity have been mixed. In a British study of 150 men circumcised as adults for penile problems, Masood ''et al.'' (2005) found that 38% reported improved penile sensation (p=0.01), 18% reported worse penile sensation, while the remainder (44%) reported no change.<ref name= "masood2005">{{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="taylor2000">{{REFjournal

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 name= "schober2008">{{REFjournal

Waldinger ''et al.'' recruited 500 men (98 circumcised and 261 not-circumcised) from five countries: the Netherlands, United Kingdom, Spain, Turkey, and the United States and studied their ejaculation times during [[sexual intercourse]]. They found that the circumcised men in the study took on average 6.7 minutes to ejaculate, compared with 6.0 minutes for the uncircumcised men. This difference was not statistically significant. The comparison excluded Turkey, which was significantly different from the other countries studied.<ref name="Waldinger2005">{{REFjournal

O'Hara and O'Hara argue that foreskin is a natural gliding stimulator of the vaginal walls during intercourse, increasing a woman's overall clitoral stimulation and helping her achieve orgasm more quickly and more often. Without the foreskin's gliding action, they suggest, it can be more difficult for a woman to achieve orgasm during intercourse.<ref name= "OHara1999">{{REFjournal

<blockquote>Clearly, the anatomically complete penis offers a more rewarding experience for the female partner during coitus. While this study has some obvious methodological flaws, all the differences cannot be attributed to them. It is important that these findings be confirmed by a prospective study of a randomly selected population of women with experience with both types of men. It would be useful to examine the role of the foreskin in other sexual activities. Because these findings are of interest, the negative effect of circumcision on the sexual enjoyment of the female partner needs to be part of any discussions providing 'informed consent' before circumcision.<ref name="ohara1998">{{REFjournal
