What Do The Eyelids, Lips, Fingertips & The Intact Penis Have in Common?

What Do The Eyelids, Lips, Fingertips & The Intact Penis Have in Common?

Take a moment to imagine the gentle flutter of eyelids in the soft, warm morning light as the sunlight filters through. Picture the tender press of soft lips in a loving kiss, a moment filled with warmth and affection.

Visualize the skillful dance of nimble fingertips on a keyboard, effortlessly gliding across the keys, creating a symphony of words and ideas.

Now, consider the natural function of the intact penis, a marvel of nature’s design, with its intricate network of blood vessels and sensitive nerve endings, providing pleasure and serving an essential role in reproduction. These body parts, seemingly distinct in purpose, are interconnected through fascinating physiological characteristics of sensitivity, protection, and intricate structural complexity.

In this article, you will discover:

  • The remarkable sensitivity shared by these body parts and their importance.
  • How they play a protective role in human physiology.
  • The unique structural adaptations that enhance their functions.

Let us explore the shared attributes of these body parts and uncover the significance behind their similarities.

1) Exquisite Sensitivity: A Symphony of Nerve Endings

One of the major similarities among these body parts is their concentration of nerve endings, giving them an extraordinary sensitivity to touch. This sensitivity is critically essential. For instance, the fingertips, with their abundance of nerve endings, enable us to manipulate objects and discern textures with finesse, facilitating skills ranging from typing to tactile recognition. 

Moreover, the lips and foreskin, exquisitely sensitive, contribute to an array of intimate sensations, heightening sexual pleasure and forging deeper emotional bonds. Meanwhile, the vigilant reflexes of the eyelids protect our eyes, reacting swiftly to the faintest hint of potential harm, ensuring their safety and well-being.

The eyelids, lips, fingertips, and intact penis are all covered in Meissner’s corpuscles, which are specialized nerve endings that serve as the gatekeepers of touch, allowing us to discern the gentlest caress or the slightest variation in texture. These microscopic sensors heighten the sensitivity of the fingertips, lips, and other touch-sensitive regions while enriching our tactile interaction with the world.

“The ridged band on the male foreskin (removed during circumcision) contains thousands of Meissner’s corpuscules, special light-touch nerve endings, located in glabrous (hairless) skin in other areas of the body, including the eyelids, lips, fingertips, and palm of the hand. During sex or masturbation, these nerve endings give a man feedback about where he is in the ejaculatory process. The frenulum (“little bridle”), the structure on the underside of the penis that keeps the foreskin in place (much as the frenulum under your tongue keeps it from flopping around inside your mouth) also contains Meissner’s corpuscules.”

2) Guardians of the Body: A Protective Role

Beyond their sensitivity, each delicate area fulfills a vital protective function. The eyelids function as stalwart shields for our precious eyes, shielding them from harmful debris and excessive light that could cause damage. As guardians of the gateway to our digestive system, the lips possess temperature and texture sensitivity, preventing harm before it can breach our bodies. 

Fingertips, despite their sensitivity, possess a resilient layer of skin that shields us from physical injury, allowing us to explore and interact with the world fearlessly. Likewise, the foreskin assumes a pivotal role in safeguarding the glans penis, preserving its sensitivity, cleanliness, and overall integrity, and ensuring optimal sexual function and well-being.

3) Unparalleled Structure: Adaptations for Excellence

In addition to their sensitivity and protective functions, these body parts showcase unique structural adaptations that enhance their capabilities. The eyelids can blink reflexively, an indispensable response to potential eye damage, ensuring our delicate ocular organs’ continuous and uninterrupted protection. The lips exhibit astonishing flexibility, essential for speech and nourishment consumption; their movements can express many emotions, fostering effective communication and connection with others. Fingertips, distinguished by their distinctive fingerprints, enhance our grip and tactile interaction with the world, allowing us to navigate objects and surfaces with precision and skill. As for the foreskin, its retractability supports optimal hygiene and sexual function.

4) Abundant in Blood Vessels: The Essence of Life

These regions, whether the fingertips tingling with sensation or the lips feeling the warmth of a smile, share a trait of being abundantly supplied with intricate networks of blood vessels. This rich vascular bed enhances its sensitivity to the world around us. It plays a pivotal role in maintaining our body’s equilibrium by regulating temperature and aiding in healing. These vessels also allow for swift adaptation to the changing environment, unveiling the body’s awe-inspiring capacity for defense and rejuvenation.

5) Mucous Membranes: The Barrier Against Pathogens

Except for the fingertips, these body parts are distinguished by mucous membranes, delicate linings that stand as the body’s first line of defense against invading pathogens. These moisture-rich barriers, distinct from the protective outer skin layer, act as vigilant shields, fortifying the body’s immune system against external threats. From the tender inner surfaces of the eyelids to the supple texture of the lips and the protective folds of the inner foreskin, mucous membranes envelop these regions, underscoring their indispensable role in shielding the body from harm.

Exploring the connections between the eyelids, lips, fingertips, and intact penis reveals their shared attributes of sensitivity, protective functions, unique structures, rich vascularization, and the presence of mucous membranes. Our bodies showcase marvels of natural design, with each part playing a critical role in our interactions and connections with the world.

Recognizing these similarities deepens our admiration for the human body’s complexity and emphasizes the importance of preserving its natural state and functions. The foreskin, akin to the eyelids, lips, and fingertips, is a vital component of this beautifully complex system, serving to protect, sense, and engage with the environment uniquely.

The 23rd of December 1947 is a day I’ll never forget. That is when I first learned, to my horror, what a circumcision was.

I was raised Roman Catholic and attended 12 years of parochial school. That day marked the last class before Christmas break, and the teacher (a nun) explained why January 1 was a holy day of obligation. (It’s the Feast of the Circumcision.)

In that moment, I understood immediately what had been done to my body. I understood why I was never comfortable there and why my clothes were always irritating me. I realized then that the head of my penis was meant to be covered. It was this unnatural exposure that was causing me to experience an almost constant state of semi-arousal. It’s not normal to be exposed that way. Being sexually aware and acting on that awareness are two, very different, things. I was an introvert, and thus a shy child, and there was no one with whom I could speak. I never broached the subject with my parents because I knew they would dismiss it, hoping I’d forget about it.

This is not considered a “normal” preoccupation, but then, having a scar encircling one’s penis isn’t “normal” either in most of the world, no matter how much our American culture insists that it is.

As a gay man who had wished since childhood for a foreskin to soothe the constant discomfort, I always found the circumcised penis ugly and to be a turn-off. It’s difficult to explain the trauma of being unable to discreetly identify intact gay men with whom to engage in sex, especially as an introvert.

This act that was done to me without my consent makes me very angry. I’ve channeled that anger into researching circumcision and the arguments for and against it for more than 75 years now. I still don’t understand why someone would amputate a normal body part simply because they have accepted without question the notion that it’s not clean.

For some reason in American culture, we don’t talk about the penis in a matter-of-fact way, and we definitely don’t talk about its foreskin—except to say that it’s dirty. What this is referring to is smegma, a word normally heard only in the context of jokes. Smegma is a natural lubricant the body produces to prevent the foreskin lining from adhering to the glans. It’s made of body oils, skin cells and moisture. Every body produces smegma—it’s between our toes and behind our ears, anywhere skin folds against itself. We just give it a quick wash and get on with our day.

The idea that a foreskin is dirty is a uniquely American notion. We’ve been cutting it off for six generations. We’re the only advanced nation where cutting off the foreskin of a male infant is routine practice, and we don’t even know why. The medical community makes all sorts of excuses that don’t hold up to science—while the rest of the advanced nations think we’re crazy. It’s sexual violence on an infant. It’s just insane.

But it’s so normalized. At a recent medical appointment, the doctor asked me to list every surgery I had ever had. I included circumcision on that list, but when I reviewed notes from the appointment, I realized she had left that one off. It has become so ubiquitous that she didn’t even mention it.

I’m 82 years old, and I’ve become more outspoken about this. I have repeatedly sent email letters to my congressmen and women and my senators, and their response is, “There, there. Don’t worry about it. We’re taking care of you.” They don’t see the harm that’s been done. I really feel that most American men have the attitude that it was done to them and there’s nothing they can do about it now. But it’s a human rights issue. And no one wants to listen.

“Do You Know?” May Is Masturbation Month

May is Masturbation Month. If you missed it, you can always indulge belatedly!

Intact America followers probably know that circumcising boys (and even girls) by doctors began around 150 years ago as a “remedy” for masturbation. Victorian era doctors believed that onanism (another term for masturbation) could cause lunacy and many other diseases, both moral and physical.

Journalist David Gollaher, in his book Circumcision: A History of the World’s Most Controversial Surgery, writes about how cereal magnate John Harvey Kellogg “recommended performing circumcision ‘without administering an anesthetic, as the pain attending the operation will have a salutary effect upon the mind, especially if connected with the idea of punishment.” Other doctors in the late 19th century advocated for the use of blistering fluids on the genitals (of boys as well as girls) to both deter and punish self-pleasuring.

Amazing, isn’t it, that this history has been lost on those who deny that circumcision harms boys and men?

If you’re over 50, you probably remember the brouhaha when Surgeon General Joycelyn Elders in 1994 talked publicly about masturbation as a natural and positive human behavior. She was ridiculed and eventually resigned from her post, but not without removing some of the stigma surrounding the subject. A year later, the sex shop Good Vibrations declared May National Masturbation Month. Put it on your calendar, but no need to wait until next year to celebrate!

A or B guys. A or B?

Two recent surveys by Intact America have raised the question by some participants of why we asked the men if their penis looked like A (an intact penis) or B (a circumcised penis), which they found either distasteful or an invasion of privacy. This is the A or B image they were talking about.
A. Intact Penis (not circumcised) and B. Circumcised Penis
The short answer is accuracy. Asking this question improves the quality of the survey results. A lot. The reason is that many men don’t know their penile status! A 2004 study of college-aged men found that 33% were mistaken or unsure of their penile status.[i] This is nothing new, a 1960 study found 14% of men were unsure; their status was confirmed by a physical examination.[ii]

More recently, in Intact America’s three, national random sample surveys (2017, 2018, & 2021) of 3298 Americans, 14% of men were mistaken or unsure of their penile status. See below for my decade-old methodology to determine whether men were mistaken or not. But first, here’s an entertaining anecdote to illustrate the problem.

You may have seen the episode of the Graham Norton Show on BBC in 2017 with guest actor Sir Patrick Stewart. He relayed the funny story about him mentioning in passing to his wife that he was circumcised. According to Stuart, in his 70s at the time, the conversation went something like this:

Stewart: I’m circumcised.
Wife: (laughs) You’re not circumcised.
Stewart: That’s ridiculous! I should know if I’m circumcised! End of conversation.
Stewart: The next day, I happened to be seeing my doctor for my annual physical. When the doc was ‘down there,’ I mentioned my disagreement with my wife, and asked, “I’m circumcised, right?”
Doctor: Not!

Surprisingly, even men who call themselves intactivists, and who are presumably knowledgeable about circumcision and male sexual anatomy, aren’t sure. A survey of intactivists found that 13% of intactivist men are mistaken or unsure.

In 2011, I wanted to learn if newborn circumcision was associated with alexithymia. Alexithymia is the inability to identify and express emotions. It is thought that it is acquired at a very early age. Such people have difficulty in relationships, social interactions, and even in therapy. But I could not examine these men who live across the United States. So, I had to develop a viable validation alternative for that peer-reviewed alexithymia and circumcision study. My solution was to ask their penile status and then compare that with their answer to the A-B image question. Entries that did not match correctly were removed from the dataset.

As it turns out, and unknown to me at the time, I’m not the first researcher to realize that self-report is inaccurate when it comes to penises. In 1992, Schlossberger found that: “Use of visual aids to report circumcision status was more accurate (92%) than self-report (68%).[iii] Wow.

Granted, the best way to determine penile status would be a physical examination. But this is so problematic on so many levels that it would be all but impossible to survey. You’d have to pass certain standards using human subjects, hire medical staff, obtain liability insurance, and of course get permission from the men to disrobe. (By the way, the proper way to determine if a man is circumcised isn’t to look for the lack of a foreskin, but the presence of a circumcision scar.)

The solution that I came up with, and one I’ve used many times since, is a three-part survey-question method. The questioning goes something like this:

Are you circumcised or intact (not circumcised)?

Don’t know

Which one of these images most looks like your flaccid (not erect) penis?


Are you restoring your foreskin?

I don’t know what this is

As you can see, this method results in much more accurate answers, and provides trustworthy data. Nevertheless, some men are not comfortable answering these questions, even to an anonymous researcher. I can appreciate that. That’s why I’ve taken steps to avoid their discomfort: 1) I inform participants that they’ll be asked personal, sexual questions, 2) tell them they can opt out now, 3) tell them they can opt out at any time, 4) mention that this data will only be used in aggregate form, and that at no time will their identity be revealed, and 5) use the image shown above obtained from a medical illustration stock image source instead of using a photo of real penises.

A study I recently conducted, and now in-press, titled “Adverse Childhood Experiences, Dysfunctional Households, and Circumcision,” also employed this method. None of the journal reviewers mentioned a problem with using this image.

So, not using this tripartite image question would make the results skewed, if not unusable, and therefore unpublishable.

Sadly, many circumcision studies being published since I created this method continue to just ask the men if they are circumcised or not, leaving us unsure of what to make of their conclusions. As scientists like to say: “Junk in, junk out.” (no pun intended!)

Ask Marilyn – Why do they keep asking me about circumcising my baby boy?

The penis advice column

Dear Marilyn:

Everything about my son’s birth was great. Except for one thing that keeps bugging me. Even though we knew early on that we’d keep him intact, people kept asking us if we wanted to circumcise him. I told my OB/GYN we didn’t want to, but on the next visit she asked. In the hospital, just about every nurse asked me even though our choice was written on my chart. This happened over and over before and after the birth. I was so angry I wanted to scream. Why do they keep asking? It made me begin to question our decision. Don’t get me wrong, I’m glad we didn’t, but geez, why weren’t they listening?

 —Alice, Fort Myers, FL

Dear Alice:

Congratulations for having the strength to protect your son’s right to his own body and withstanding the pressure of those who tried to coerced you to cut off the most sensitive part of his genitals. Circumcision is BIG business—a $2 billion-dollar-a-year industry for an unnecessary and harmful amputation, which is why doctors and nurses “sell” it so hard.

Doctors and nurses won’t admit it, but they know that circumcision is excruciatingly painful and traumatic. That’s why they do their genital cutting behind closed doors and prevent parents from hearing the screams or watching their babies suffer.

By keeping parents in the dark, health professionals can convince vulnerable and exhausted parents, right after their child is born, to circumcise their baby. If more parents knew what circumcision involves, they could stand strong and resist the pressure.

For example, a colleague and I videotaped a circumcision at the hospital where we worked. A childbirth educator showed the circumcision video to her class, and not one of the mothers circumcised their sons as a result. The educator showed it again to a second class of mothers. They didn’t circumcise their babies either—except for one doctor who was taking the class. Even worse, the doctor insisted that our video be censored. That’s how much doctors dread letting the truth slip out.

Fortunately, several anti-circumcision movies are available now that include actual circumcisions. I suggest watching The Circumcision Movie. Not only will you see that you and your husband were correct to protect your son, you’ll also learn that you are not alone in denouncing this anachronistic blood ritual.
