Why Philosophers and Physicists Understood Sexual Desire Better Than Your Therapist

What coaching 100+ men to hotter sex and three dead philosophers taught me about desire in marriage.

I have spent five years building a system for married men who want more sex with their wives.

I tested the first version in my own marriage and have 1:1 coached over 100 men through it. I have mapped 10 Desire Killers and 24 Desire Levers organized into 3 Desire Drivers for that. I have built a free Desire Killer Diagnostic tool and am building a Diagnostic for the Desire Drivers. I think in frameworks and build-measure-learn loops. I am, by training and by temperament, an engineer.

And for the past few months, something has been simmering in me that does not fit neatly into any of my frameworks.

Then, a week ago, I read something Dan Koe wrote about why essays matter, about how they are one of the last forms of thinking where you write to discover rather than to package what you already know. And I thought: yes. That is what this needs to be.

Because what I want to talk about is something I have not heard anyone else in this space name. Not the sex therapists, the evolutionary psychologists, the dating coaches, the manosphere voices or the couples counselors. Nobody is talking about this.

I think it is the actual substance underneath sexual desire, which is especially relevant to marriage. The thing that everything else, technique, communication, attraction, polarity, sits on top of.

I am going to try to articulate it here, the way Dan Koe describes: writing to find out what I think.

Let’s see where this goes.

The Philosophers Were Already There

The observation that life is movement, not stasis, is not new. Philosophers have been circling it for centuries, each arriving at the same territory from a different direction.

In 1907, Henri Bergson published Creative Evolution and introduced the term élan vital, the vital impulse. For Bergson, life is not well understood as a static mechanism; it is duration, development, and creative movement. In French, prendre son élan describes an athlete gathering momentum before a leap. An élan of love is an uncontrollable surge of feeling. Bergson chose the word deliberately, because it captures something that mechanical descriptions of life miss entirely: the forward thrust, the becoming, the constant creation of something that did not exist a moment ago.

“To exist is to change,” Bergson wrote. “To change is to mature, to mature is to go on creating oneself endlessly.”

Nietzsche approaches a related question from a very different angle. His concept of the will to power, widely misunderstood as a desire to dominate others, points to something far more interesting when read carefully. In a posthumous notebook passage, Nietzsche wrote that he had found “strength where one does not look for it: in simple, mild, and pleasant people, without the least desire to rule.” A major line of interpretation treats Nietzsche’s will to power not as mere domination of others, but as growth through overcoming resistance and self-overcoming. The philosopher Bernard Reginster puts it precisely: “The agent in pursuit of power does not seek achievements, so to speak, but achieving. What he needs are fresh, new, perhaps greater challenges. And this explains why the pursuit of power assumes the form of growth, or self-overcoming.”

Not domination. Growth. Not arriving. Becoming.

Spinoza, writing in the seventeenth century, uses the term conatus for the striving by which each thing persists in its being; in his moral psychology, joy is associated with an increase in one’s power of acting. This is worth sitting with, because it redefines joy in a way that most modern men have never considered. Joy is not a reward you receive for completing a task or reaching a goal. Joy is the direct experience of your own expanding capacity. When you learn something new, when you build something that works, when your body grows stronger, when you feel your capability increasing in any domain, that feeling is not a side effect of success. It IS the thing. Spinoza writes that appetite “is nothing but the very essence of man, from whose nature there necessarily follow those things that promote his preservation,” and adds that desire is appetite of which we are conscious.

These three philosophers do not teach the same doctrine, but they converge on a useful family resemblance: life is not only maintenance; it also involves striving, development, and the exercise or increase of power. And the moment that striving stops, something essential dims, even if everything on the outside looks fine.

What My Engineering Degree Never Told Me About Marriage

In 1944, the physicist Erwin Schrödinger published What is Life?, in which he asked: how do living organisms maintain their extraordinary internal order when the second law of thermodynamics implies that entropy increases in isolated systems?

His answer: living systems survive by “feeding on negative entropy,” a shorthand he later noted physicists would state more precisely in terms of free energy. A living organism is not well described as a static thing; it is an ongoing process that maintains order while avoiding decay toward equilibrium. In Schrödinger’s biological framing, if a living organism can no longer maintain itself away from equilibrium, it decays toward thermodynamic equilibrium, which is a way of describing death in the organismic sense.

I studied mechanical engineering at ETH Zurich and encountered thermodynamics as a core discipline. For years, entropy was something I associated with engines and heat transfer, not with marriage. But the connection, once I saw it, was hard to unsee.

A man who has settled into comfortable equilibrium in his marriage, who is stable, balanced, not in chaos but also not in motion, has, in the thermodynamic metaphor, reached room temperature. He is not in crisis. He is not suffering. He has simply stopped doing the thing that living systems do: importing new order, creating new complexity, maintaining themselves away from the equilibrium that is, in the biological sense, death. His wife does not experience this as a problem. She experiences it as an absence. As the feeling that something is missing. As the slow realization that the man she married is physically present and energetically gone.

How Marriage Slowly Kills the Thing She Married You For

The forces that kill aliveness in marriage are not dramatic. They are the same forces that make marriage functional. That is what makes them so dangerous.

Comfort narrows. When life is comfortable, you stop seeking the experiences that used to make you feel alive, because you do not need them anymore. The restaurant you always wanted to try becomes the restaurant you always go to. The hobby that challenged you becomes the routine you maintain. The edge of your comfort zone, which is where aliveness lives, recedes inward until your entire life fits inside a zone so small you can navigate it with your eyes closed.

Routine flattens. The human nervous system requires novelty to stay alert. When every day follows the same pattern, the mind stops paying attention. Not consciously. Physiologically. You literally stop noticing. The way your wife looks in the morning. The taste of your coffee. The texture of the air when you walk outside. These are not small things. They are the raw material of aliveness. And routine buries them under a layer of automation so thick that you forget they exist.

Optimization kills play. This is the one I find most insidious, because it affects precisely the men who are most successful in other domains. The optimizer treats his life as a system to be improved. He tracks, measures, eliminates waste, maximizes output. He applies to his marriage the same logic he applies to his calendar: remove friction, increase efficiency, produce predictable results. And in doing so, he eliminates the variability, the spontaneity, the play, the productive waste that Bergson would recognize as the creative movement of life itself. An optimized life is an efficient life. It is also, often, a dead one.

Obligation replaces wanting with having-to. The man who trains because he wants to feel strong is alive. The man who trains because he “should” is performing a duty. They look identical in the gym. They feel completely different to be around. And their wives can feel the difference, because obligation carries a weight that wanting does not. Every domain of your life where “I want to” has been replaced by “I have to” is a domain where aliveness has been substituted with compliance.

And seriousness. The relentless, grinding seriousness of the man who has forgotten how to play. Who approaches everything, including his marriage, including sex, as a problem to be solved rather than an experience to be had. The manosphere is full of these men: disciplined, goal-oriented, optimized, serious, and dead. Their wives respect them. Their wives do not desire them. Because desire does not respond to seriousness. Desire responds to aliveness. And aliveness, at its core, is closer to play than it is to discipline.

What I Mean When I Say Aliveness

I keep thinking in the word aliveness and then second-guessing it. Aliveness sounds like energy, but it’s not just energy. It sounds like enthusiasm, extraversion or “good vibes”, but it’s not that either.

Let me try it this way...

What I am calling aliveness draws on Nietzsche’s will to power, Bergson’s élan vital, Spinoza’s conatus, and Schrödinger’s description of life as maintaining order against decay toward equilibrium. In practical terms, it is a man in contact with his own wanting. Not wanting in the sense of craving or neediness, but the conscious experience of your own striving to expand, to become, to increase your capacity in the world.

The man who burns for something he is creating. Who notices the weight of the barbell and the quality of the light and the way his wife laughs. Who feels things fully instead of managing every experience into a smooth, predictable, emotionally flat frequency. Who gets genuinely angry, laughs until it's embarrassing, grieves when something is worth grieving. A man who plays, not as a productivity hack or a stress management technique, but because play is one of the purest expressions of being alive.

What I Now Believe About Desire In Marriage

This is what the simmering thought turned into, after five years of working on this problem in my own marriage and with over 100 men, and one Dan Koe-Style essay to force my thinking into words:

Your wife’s sexual desire for you is, above all else, a response to your aliveness.

Everything else, the sex techniques, the communication, the attraction, the polarity, are real and worth learning. But without aliveness underneath it, none of it carries the charge that makes your wife crave you sexually. And with aliveness underneath it, even imperfect execution produces sexual desire, because your wife is not responding to what you do. She is responding to how you are.

Dead men do not get desired. They get tolerated, managed, accommodated, and eventually ignored. Because desire is, at its deepest level, a biological response to the life force in another person. It always has been. Bergson knew it. Nietzsche knew it. Spinoza knew it. Schrödinger gave it a physical framework. Your wife knows it in her body, even if she does not have the words for it.

When I Tested This Against Everything I Know

That conviction did not arrive from philosophy alone. Writing this, I keep testing the aliveness lens against everything else I know about sex in marriage. And what I find is that it holds, not just in philosophy and physics, but in the practical work that serious people have been doing in the relationship space for decades.

The dating and PUA coaches who teach men to carry confidence when meeting women are actually building one dimension of aliveness. The man who walks into a room and takes up space without apology, who holds eye contact without flinching, who moves at his own pace is a man in contact with his own wanting. They name it “confidence” or “frame” or “presence.” The underlying variable is aliveness.

The couples therapists who help men regulate their emotional volatility, who teach them to feel their anger without exploding and their grief without collapsing are addressing another dimension of aliveness. The emotionally regulated man is not a flat man. He is a man who can feel the full range without being destroyed by it. That capacity, to feel fully without numbing, is one of the clearest expressions of aliveness.

Esther Perel, when she writes about eroticism in long-term relationships requiring “vibrancy and vitality,” when she argues that desire needs mystery and that mystery requires two people who are genuinely separate, genuinely other to each other, she is describing aliveness in relational terms. The man who has his own interior life, his own direction, his own fire that exists independently of his wife, is the man who remains mysterious and alive.

The serious thinkers in what gets loosely called the manosphere were pointing at aliveness long before I had the word for it. Rollo Tomassi, the most rigorous voice in that space in my view, insists that a man's primary orientation must be toward his own mission, not toward managing his wife's approval. Tomassi's concept of 'frame', the idea that a man with a genuine world of his own is fundamentally more desirable than a man who has made his wife the center of his universe. Through the aliveness lens, that is conatus. His wife enters his world because his world is worth entering. Tomassi also observed, that genuine desire cannot be negotiated. A woman's desire for a man is a response she comes to on her own. To paraphrase it in the aliveness context, sexual desire is a response to aliveness. You cannot negotiate your way into being alive. You can only be alive or not.

What My Own Coaching Experience Reveals

I have created the Desire Engineering System for married men with 10 Desire Killers, three Desire Drivers and the 24 Desire Levers below it, to produce one result: hotter sex with your wife. That is what men come to me for. That is what I measure.

But something has been nagging at me while writing this essay.

A number of the men I have coached, not all of them, but enough that I noticed, came back and said something I always filed under “side effect.” They say versions of: “I don’t know how to explain this, but my life just feels more alive now.” Or: “Something shifted that I wasn’t expecting.” Or: “The sex is better, but honestly that’s almost secondary to how differently I feel about my own life.”

I always heard that as: better sex produces aliveness. The sex improved, so the man feels better about everything.

Writing this essay, I am not sure that is the right direction of causality.

What if the coaching produced aliveness first and the better sex was the downstream effect? What if the Desire Drivers I mapped are, at their core, something like “aliveness restoration protocols”? And what if the reason they work is not primarily because they make a man more desirable to his wife, but because they reconnect him to his own wanting. And then his wife automatically responds to that?

Or, and this might be closer to the truth, it is not linear in either direction. It is a loop. The coaching reconnects you to aliveness. Aliveness produces desire in your wife. Better sex deepens your sense of being alive. Which produces more desire. Which produces better sex. The loop feeds itself.

I built the system to produce better sex. I may have been building an aliveness restoration engine without knowing it.

For me, that is the most interesting thing I have discovered writing this essay. I am not done thinking about it.
