Circumcision, Modesty and Sexual Kinks

Because circumcision is performed on the sexual organ it is intertwined with sexuality even though many people don't really regard it as something obviously connected (e.g. because they think of circumcision as a religious obligation not to be discussed in the context of sexuality).

So there is a reason why the Chinese keep inventing new medical gadgets by the dozen to perform circumcisions.

Does Circumcision Reduce Men’s Sexual Sensitivity?

Not according to this study.

The other 34 studies showed similar results. In several, compared with men with intact foreskins, those who’d been circumcised often said their penises felt more erotically sensitive. In addition, circumcision had no effect on rates of premature ejaculation or erection or ejaculation difficulties.

A review article about the effects of circumcision on penile sensitivity from a histological point of view.

Histological Correlates of Penile Sexual Sensation: Does Circumcision Make a Difference?

This sums it up:

We retrieved 41 publications on penile structure. Considered in the light of 12 reporting physiological measurements, our evaluation finds that sexual response is unlikely to involve Meissner's corpuscles, whose density in the prepuce diminishes at the time of life when male sexual activity is increasing. Free nerve endings also show no correlation with sexual response. Because tactile sensitivity of the glans decreases with sexual arousal, it is unrelated to sexual sensation. Thermal sensitivity seems part of the reward mechanism of intercourse. Vibrational sensitivity is not related to circumcision status. Observations that penile sexual sensation is higher post circumcision are consistent with greater access of genital corpuscles to sexual stimuli after removal of the prepuce. This is based on the distribution of these corpuscles (which are located in the glans) and, in uncircumcised men, the position of the retracted prepuce during intercourse, rather than any change in the number of genital corpuscles. The scientific literature suggests that any sexual effect of circumcised men may depend solely on exposure of the glans and not on the absence of the prepuce.

Adult Male Circumcision: Effects on Sexual Function and Sexual Satisfaction in Kisumu, Kenya

The bottom line:

Adult male circumcision was not associated with sexual dysfunction. Circumcised men reported increased penile sensitivity and enhanced ease of reaching orgasm. These data indicate that integration of male circumcision into programs to reduce HIV risk is unlikely to adversely effect male sexual function.

Erogenous Parts

One of the weirdest things that keeps popping up all over the Internet is the claim that the glans penis is not erogenous, and only the foreskin provides erogenous sensation. I am sure it is meant to be a figure of speech to emphasize a point, but someone might actually take it literally.

To be fair, there is another (much shorter) list of  evidence that the foreskin is needed for pleasure.
