(excerpts from a letter to Rosemary Romberg, author of Circumcision: The Painful Dilemma, from a man in Florida, circumcised at 25)

...There are no words to describe how powerful, how compelling a penis with a foreskin is and how one's life revolves around it. Circumcision did not eliminate masturbation, but it took away its intense pleasure, its extreme sweetness ... It became dull, uninteresting, boring....Foreskins are cut off because they are extremely pleasurable ... No one who has been clipped in infancy even realizes it ... Foreskins are cut off to get the young man's mind off sex ... They are just too much fun....it was wet like the inside of my mouth for 25 years.

...Local anesthesia into the perineum and the freehand method were used ... they gave me a pill to try and calm me down ... The whole thing took only a few minutes once the anesthesia took hold. They told me there would be no pain....there was no pain at all when they made the dorsal slit and cut the foreskin free at the coronal sulcus, first around one side of the glans, then the other ... They injected a few drops of extra anesthesia directly into it [the frenulum] ... Then they grasped it with hemostats in several places, pulled it, poked at it, and asked me half a dozen times if I could feel anything. After I said "No" each time, they pulled it well out of its little V-shaped groove and quickly snipped it.

...with the first snip a tremendous flash of blinding white pain surged through my entire body! I thought I had been electrocuted and was dead ... The pain was not just in my penis, but throughout my entire body from head to toe.

...The pain was the worst I have ever had in my entire life, before or since. I cannot any imagine pain possibly being worse ... the horrible pain. [It is now known that babies feel as much pain when they are circumcised as anyone else would.]...Imagine if it had not been anesthetized at all! [Most babies circumcised in the U.S. are circumcised without anesthesia.]

...I wanted everyone who had not been through it to experience it....Circumcision is ... getting it [one's penis] back broken, bleeding, in great pain, with its most delicate, sensitive parts ... cut off, permanently weakened....the glans eventually dried out (a process that took over a year).

...Before circumcision my erections would be extremely strong ... Now the erection is weaker and the penis does not get so terribly stiff.

"A remedy [for masturbation] which is almost always successful in small boys is circumcision. The operation should be performed by a surgeon without administering an anesthetic, as the pain attending the operation will have a beneficial effect upon the mind."—John Harvey Kellogg, MD [the breakfast cereal tycoon] Plain Facts for Old and Young, 1888

Hi Gang:

Some comments. Obviously orgasm is possible after circumcision. If it were not, then the population of the USA would have decreased significantly over the past 100 or so years. The question is the degree of personal enjoyment of the "orgasmic" experience. I believe there would be little debate that circumcision "significantly" reduces the sense of enjoyment of the sexual experience and most specifically that of the actual orgasm. The more sensation one experiences, the greater this "Orgasmic High" will be. In a survey we conducted some years ago of adult males, the frenulum and foreskin glans sulcus area was repeatedly identified as the most sensitive area of the penis by natural INTACT males. The glans sensitivity cannot begin to compare with this sensitivity of the frenulum sulcus region. If damage by circumcision, which is almost certain, that sensitivity is going to be seriously reduces or eliminated. After all, was this not the purpose of circumcision to deter masturbation?—Regards, Jim Peron
