http://www.cirp.org/library/sex_function/ The human foreskin is highly innervated,5 21 29 and vascularized29 sensitive erogenous tissue.6 29 It plays an important role in normal human sexual response and is necessary for normal copulatory behavior.40 An understanding of this role is now emerging in the scientific literature. Removal of the foreskin (circumcision) interferes with normal sexual function. The foreskin provides mechanical functions to facilitate intromission and penetration. Several authorities observe that the penis enters the vagina without friction as the foreskin unfolds.4 9 10 11 Taves (2002) reported that excision of the foreskin by circumcision increases the force required to penetrate by ten-fold.51 Shen et al. reported 43.1 percent of men cirumcised as adults experience difficult penetration.59 After penetration, the foreskin provides a gliding action that greatly reduces friction,4 9 11 15 41 49and vaginal dryness.27 40 50 55 Elasticity. The foreskin has a layer of smooth muscle tissue called the peripenic muscle,1 which is part of the dartos muscle.1 39 The contraction and expansion of the muscle fibers in this layer give the foreskin great elasticity and are important in erogenous sensation. Lakshmanan & Prakash report a "mosaic of muscle tissues and elastic fibres" contained between the two layers of the foreskin, which keep the foreskin snugly against in the glans penis in a close fit.15 The muscle fibres must stretch to allow the foreskin to retract over the glans and contract again when the foreskin returns to its normal forward position. The expansion and contraction of the muscle fibres during coitus allows the foreskin to stretch. The stretching deformes the Meissner corpuscles and produces sensation.68 The nerve bundles run alongside the dartos muscle.40 The stretching puts tension on the nerve endings contained within the foreskin. The nerve endings deform and generate pleasurable erotic sensations to the central nervous system and inputs to the autonomic nervous system, which plays a role in controlling erection and ejaculation.57 68 Taylor (2003) reports preliminary evidence that stretching of the foreskin produces contractions associated with ejaculation.58 Taylor reports that the ridged band of the foreskin is reflexogenic and produces contractions that result in ejaculation.68 Premature ejaculation. Lakshmanan & Prakash (1980) report that the foreskin impinges against the corona glandis during coitus.15 The foreskin, therefore, tends to protect the corona glandis from direct stimulation by the vagina of the female partner during coitus. The corona is the most highly innervated part of the glans penis.19 Zwang argues that removal of the foreskin allows direct stimulation of the corona glandis and this may cause premature ejaculation in some males.32 O'Hara & O'Hara (1999) report more premature ejaculation in circumcised male partners.41 The presence of the foreskin, therefore, may make it easier to avoid premature ejaculation, while its absence would make it more difficult to avoid premature ejaculation. Inability to ejaculate or delayed ejaculation. While some circumcised males may suffer from a tendency toward premature ejaculation, others find that they have great difficulty in ejaculating.50 The nerves in the foreskin and ridged band are stimulated by stretching,18 57 amongst other movements. If those nerves are not present, Money (1983) argues that excision of these stretch receptors by circumcision may make ejaculation take longer.18. Some circumcised males may have to resort to prolonged and aggressive thrusting to achieve orgasm Value to female partners. The foreskin has long been known to be valuable to the female partner.8 16 The presence of the foreskin is reported to be stimulating to the female.41 45 55 Women are more likely to experience vaginal dryness during sex with a circumcised partner.24 28 62 The unnatural dryness may make coitus painful and result in abrasions.28 41 50 The vaginal dryness may be mistakenly attributed to female arousal disorder

Circumcision affects sex. It makes penetration difficult, if not painful. And most circumcised men do lose much sensation and are unable to orgasm when they get older and this happens because the head progressively desensitizes. Because circumcision removes the movable skin, sex becomes more like thrusting a dowel in and out. The hardened coronal ridge of a circumcised man scrapes out the vaginal lubrication and abrades the vaginal walls causing increased dryness and soreness. Most women with circumcised lovers, myself included, are like "just get this over with" because their husband or lover is banging harder and longer and it is no longer enjoyable.

I was circumcised as an infant because my parents are Jewish. My circumcision wound didn't close until I was 4 years old and I needed surgery to close the wound. I later had two more surgeries so I could urinate properly because the scar tissue from my circumcision blocked my urethra. I can't have an erection without pain because I don't have enough skin on my penis. My wife and I have been married for almost 5 years and we've yet to have intercourse. It's been hard on our marriage but my wife has been amazing. I plan to undergo foreskin restoration in hopes to reverse some of the problems my circumcision has caused me. If my wife and I are lucky enough to be blessed with a son, we will definitely NOT be circumcising him!
