Innervation
Die Vorhaut ist reich an spezialisierten Nervenendigungen und spezialisiertem erogenem Gewebe. Diese spezialisierten Nervenendigungen umfassen (Meissner-Körperchen, Vater-Pacini-Körperchen, Ruffini-Körperchen und Merkel-Zellen), die bereits leichteste Berührungs- und Temperaturreize detektieren können.
Im Gegensatz zur Vorhaut besitzt die Glans penis fast ausschließlich nicht-spezialisierte, freie Nervenendigungen (sogenannte Nozizeptoren), die nur grobe Reize wie etwa starken Druck oder hohe Temperatureize detektieren können, die vom Gehirn als Schmerzen wahrgenommenen werden.
Cold und Taylor, welche die Innervation des Präputiums des Penis ausführlich untersuchten, erklärten:
„Die Glans penis ist vorwiegend durch freie Nervenendigungen innerviert und besitzt hauptsächlich nur protopathische Sensibilität. Protopathische Sensibiltät bezieht sich auf gröberen, schlecht lokalisierten Empfindungen (einschließlich Schmerz, einige Temperaturempfindungen und bestimmte Wahrnehmungen von mechanischem Kontakt). In der Glans penis sind nur wenig [spezialisierte Nervenendigungen] vorhanden, und diese finden sich hauptsächlich entlang des Eichelkranzes und des Frenulums. Im Gegensatz dazu hat das gefurchte Band der männlichen Vorhaut an der mukokutanen Grenze eine hohe Konzentration an [spezialisierten Nervenendigungen].“

International Adoption Agencies of Circumcision
3. März 2013 ·
What we know about human genital anatomy:
What we call "male circumcision" amputates the mobile portion of the penis and thousands of the most specialized pressure-sensitive cells in the human body - Meissner’s corpuscles for light touch and fast touch, Merkel’s disc cells for light pressure and texture, Ruffini’s corpuscles for slow sustained pressure, skin tension, stretch, and slip, and Pacinian corpuscles for deep touch and vibration are found only in the tongue, lips, palms, nipples, fingertips, the clitoris, and the Ridged Band of the male foreskin. These cells process tens of thousands of information impulses per second. These are the cells that allow blind people to "see" Braille with their fingertips. Cut them off and it's like trying to read Braille with your elbow. Information from tactile sensitivity gives humans environmental awareness and control. With lack of awareness comes lack of control. Luckily, for those who have them, Nature has mandated that these four types of mechanoreceptors do not age-degrade like the rest of the body's cells. To say that amputation of the clitoris or the mobile roller-bearing portion of the natural penis and consequently thousands of these specialized nerve cells does not debilitate is grossly illogical denial of mechanical and somatosensory facts.

Basic Human Genital Anatomy #101
Neurologically, the most specialized pressure-sensitive cells in the human body are Meissner’s corpuscles for localized light touch and fast touch, Merkel’s disc cells for light pressure and tactile form and texture, Ruffini’s corpuscles for slow sustained pressure, deep skin tension, stretch, flutter and slip, and Pacinian corpuscles for deep touch and detection of rapid external vibrations. They are found only in the tongue, lips, palms, fingertips, nipples, and the clitoris and the crests of the ridged band at the tip of the male foreskin. These remarkable cells process tens of thousands of information impulses per second and can sense texture, stretch, and vibration/movement at the micrometre level. These are the cells that allow blind people to „see” Braille with their fingertips. Cut them off and, male or female, it’s like trying to read Braille with your elbow.
Physiologically, the clitoris is richly endowed with thousands of these specialized pressure-sensitive nerves and the clitoral foreskin is virtually bereft of them. The ridged band at the tip of the the penile foreskin is richly endowed with thousands of these same specialized pressure-sensitive nerves and the glans is virtually bereft of them. Lightening speed feedback by somatosensory transduction from such tactile sensitivity gives humans intense pleasure, environmental awareness, and control. Cut off these super-sensitive cells and with lack of awareness comes lack of control. To say that amputation of the clitoris or amputation of the mobile roller-bearing-like portion of the natural penis, and consequently thousands of these specialized nerve cell interfaces, does not permanently sub-normalize a woman’s or a man’s natural capabilities and partially devitalize their innate capacity for gliding action tactile pleasure is grossly illogical denial of the bio-mechanical and the somatosensory facts of human genital anatomy.
Mechanically, the natural vaginal and penile lubricants are kept inside the vagina during male/female intercourse by the organic seal effect of the mobile penile foreskin. The mechanoreceptors in the buried legs of the intact clitoris straddle the entroitus of the vagina and are stimulated by the identical mechanoreceptors in the thick bunching accordion folds of the mobile penile foreskin. The clitoris and the penile foreskin are also intensely vascular – thickening when stimulated. Millions of years of trial and error evolutionary forces have synchronously engineered the human sex organs to function synergistically. We can be sure Nature has evolved (if you prefer, God has created) these differences and duplications for a reason. The brilliantly engineered unaltered female body is the perfect match for the equally brilliantly engineered design of the natural penis; they evolved together to compliment each other and they function collaboratively to achieve two common goals – mutual pleasure and insemination.
A woman can live without the sensitivity of the visible part of her clitoris. A man can live without the mobile and most sensitive part of his penis. But, both men and women are better off with their natural fine-touch parts intact – all of them. And so are their sexual partners.

"Da die Vorhaut ein sensorisch empfindlicher Teil des männlichen Genitales ist, unterliegt auch die vollständige und irreversible Vorhautentfernung, einer klaren und medizinisch-orientierten Indikation. Aus medizinischer Sicht existiert kein nachvollziehbarer Grund, einem beschwerdefreien Jungen dessen asymptomatische Vorhaut zu entfernen."
