Protection: Just as the eyelids protect the eyes, the foreskin protects the glans and keeps its surface soft, moist, and sensitive. It also maintains optimal warmth, pH balance, and cleanliness. The glans itself contains no sebaceous glands--glands that produce the sebum, or oil, that moisturizes our skin. The foreskin produces the sebum that maintains proper health of the surface of the glans.

Immunological Defense: The mucous membranes that line all body orifices are the body's first line of immunological defense. Glands in the foreskin produce antibacterial and antiviral proteins such as lysozyme. Lysozyme is also found in tears and mother's milk. Specialized epithelial Langerhans cells, an immune system component, abound in the foreskin's outer surface. Plasma cells in the foreskin's mucosal lining secrete immunoglobulins, antibodies that defend against infections.

Erogenous Sensitivity: The foreskin is as sensitive as the fingertips or the lips of the mouth. It contains a richer variety and greater concentration of specialized nerve receptors than any other part of the penis.[15] These specialized nerve endings can discern motion, subtle changes in temperature, and fine gradations of texture.

Coverage during Erection: As it becomes erect, the penile shaft becomes thicker and longer. The double-layered foreskin provides the skin necessary to accommodate the expanded organ and to allow the penile skin to glide freely, smoothly, and pleasurably over the shaft and glans.

Self-Stimulating Sexual Functions: The foreskin's double-layered sheath enables the penile shaft skin to glide back and forth over the penile shaft. The foreskin can normally be slipped all the way, or almost all the way, back to the base of the penis, and also slipped forward beyond the glans. This wide range of motion is the mechanism by which the penis and the orgasmic triggers in the foreskin, frenulum, and glans are stimulated.

Sexual Functions in Intercourse: One of the foreskin's functions is to facilitate smooth, gentle movement between the mucosal surfaces of the two partners during intercourse. The foreskin enables the penis to slip in and out of the vagina nonabrasively inside its own slick sheath of self-lubricating, movable skin. The female is thus stimulated by moving pressure rather than by friction only, as when the male's foreskin is missing.

The foreskin fosters intimacy between the two partners by enveloping the glans and maintaining it as an internal organ. The sexual experience is enhanced when the foreskin slips back to allow the male's internal organ, the glans, to meet the female's internal organ, the cervix--a moment of supreme intimacy and beauty.

The foreskin may have functions not yet recognized or understood. Scientists in Europe recently detected estrogen receptors in its basal epidermal cells.[24] Researchers at the University of Manchester found that the human foreskin has apocrine glands.These specialized glands produce pheromones, nature's chemical messengers. Further studies are needed to fully understand these features of the foreskin and the role they play.

Is puberty embarrassing?

I do not think you have anything to worry about. If you were asking these questions at age of 18 or 20 years, then I could understand your concerns. Just give yourself a few years and you should be ok. As for the foreskin not retracting, you know, it is so silly to think that you have to do things to hurt yourself or to be like somebody else. Just because someone says you have to retract your foreskin why do you think you have to do it? The reasoning is not correct that if a foreskin isn't retractable it can cause problems with cleaning and sex, and if it doesn't retract it's not functioning properly. There actually are millions of men in the world at any one time, myself included, who do not retract their foreskin. I have a number of current patients in a similar condition and have, in the past, treated men in Europe, Asia and other countries with the condition of tight foreskin. Not one that I have personally met and not one that I have ever read about has a problem with cleaning. Nor do they have problems with masturbation or sex. And I have to join with them in saying that it is ridiculous to suggest that our penises are not functioning properly. Your penis and your foreskin are a unique team. They work together almost always in perfect harmony. Some guys have a foreskin that retracts, so they retract it. Some guys have a foreskin that does not retract, so they leave it alone. Some guys have had their foreskin removed and no longer have a choice. If you are watching videos, then the guys are probably porn stars and they do so much drugs and other stuff that their sexuality is no longer normal in any case. I would not worry about them. If your foreskin does not easily retract, do not try to force it to. It does not have to. You do not have to pull the foreskin back to put a condom on, to masturbate, or to have sex. It is an absolute nonsense to think so. Only fools will tell you this is necessary. Some people label a tight foreskin as phimosis. Generally people with a tight foreskin do not have phimosis, they just have a tight foreskin. There are millions of guys in the world with this condition which is quite normal. The only abnormal thing is when you try to stretch a foreskin that does not need to be stretched or try to use medications that rarely have any beneficial result. The unfortunate thing is that retraction has been taught, mainly in USA, because personal hygiene was not taught. Washing a penis with the foreskin covered (not retracted) is very easily achieved and very efficient. Any boy or man can be shown how to do it if they are having a problem. The same goes for masturbation or sex. Many will argue that it is much more effective and it certainly feels great. I cant compare it to an open foreskin, because I have never done it that way. Just leave your foreskin as it was intended to be. Anything you do to yourself that hurts is normally not a good thing to do, so don't do it.


Why do some men have skin over there penis?

Do you mean why do men retract their foreskins and expose the end (the glans) of their penis? This generally occurs all by itself when the penis is erect, as the normally loose foreskin is stretched tight when the penis stiffens and extends in length. Many guys also retract the foreskin by hand when they urinate because it reduces the likelyhood of their urine splashing around, it also avoids trapping urine droplets under the foreskin. All guys should retract their foreskin when bathing or showering to ensure that they wash their penis properly and thus avoid unpleasant smells and infections.

How is infant male circumcision performed?

In circumcision of infants, the foreskin is pulled tightly into a specially designed clamp, and the foreskin pulls away from the broadened tip of the penis. Pressure from the clamp stops bleeding from blood vessels that supplied the foreskin


What is a long foreskin?

By examination of the word 'long' one would assume the question is referring to a foreskin greater than average. Average foreskin covers the glans of the penis completely when soft. When erect average foreskin typically slides back and exposes some if not all of the glans. If a man has 'long' foreskin, by description alone it suggests that the foreskin is of a greater/longer amount than average. Some men with longer foreskins can have an erection with no exposure of the glans. In other cases the foreskin can be long enough to cover the glans during erection with excess at the tip. Typically the position of the foreskin is dependant upon the elasticity and size of the frenum, which attatches the foreskin to the underside of the glans. The more flexible and abundant the frenum is, the more likely the foreskin is able to slide up and down.
