The simplest answer is that the opportunity to do something and the desire to act on it are two different things. A man who does not cheat when he could has made a choice, and the reasons vary considerably from person to person.
Some men simply love their wives. Not as an abstraction, but in a specific, daily way that makes the prospect of betrayal feel genuinely unappealing. The other woman, however attractive, represents a disruption to something they value more than novelty.
Some are risk calculators. They see what infidelity costs when it comes apart, and they have watched it come apart in other marriages. The beautiful young woman is also a potential catastrophe: a divorce, estranged children, financial ruin, public humiliation. The arithmetic does not work in their favor and they know it.
Some men have a strong identity built around being trustworthy. Their self-image depends on being the kind of person who keeps his word. Cheating would not just damage the marriage; it would damage how they see themselves, and that matters to them more than the short-term gain.
There is also the factor of genuine satisfaction. A man who feels respected, desired, and at ease in his marriage experiences temptation differently than one who feels unseen. This does not mean unhappy men always cheat, but it does mean that happiness at home changes the weight of what is being offered elsewhere.
Finally, some men have a moral framework, religious or otherwise, that they take seriously enough to live by rather than simply profess. Belief, when it is real rather than performative, shapes behavior.
The interesting thing is that none of these explanations require the man to be a saint. They require him to have something he values more than what is being offered. That is less about virtue in the abstract and more about what a particular man, in a particular life, has decided matters.
Studies on men with high status, wealth, and access consistently show elevated rates of infidelity. Power reduces inhibition, increases opportunity, and often comes with a social environment where other men behave the same way, which normalizes it further. The research on politicians, executives, and celebrities broadly supports the idea that access and infidelity correlate.
It might be that fidelity among men with serious opportunity is the exception rather than the rule, and that the men who resist are outliers shaped by unusually strong marriages, unusually strong religious conviction, or an unusually powerful fear of consequences. That would not be a flattering portrait of men as a class, but flattery is not the same as accuracy.
Evolutionary psychology would say men evolved in an environment where reproducing with multiple women increased the number of offspring carrying their genes. A man who felt strong desire for sexual variety and acted on it left more descendants than one who did not. Over thousands of generations, that preference got baked in. The contemporary man inheriting that psychology did not choose it any more than he chose his height.
Robert Trivers’ work on parental investment is foundational here. Because women bear the greater biological cost of reproduction, they evolved to be more selective. Men, who can in principle reproduce with minimal investment, evolved toward a greater appetite for novelty and number. David Buss has documented this cross-culturally at length, finding that men across very different societies consistently report stronger desires for sexual variety than women report.
The specific scenario of a man with wealth and status having access to attractive young women maps almost perfectly onto what evolutionary psychology predicts would maximize male temptation. Youth and physical attractiveness are signals of fertility. High status in the man correlates historically with resources that could support offspring. The setup is, from a purely biological standpoint, close to optimal conditions for the evolved drive to fire hard.
Where evolutionary psychology gets more careful is in distinguishing desire from behavior. The framework predicts strong temptation, not inevitable action. Humans also evolved the capacity for long-term pair bonding, for reputation management, for caring deeply about their children’s welfare in stable households. These pressures cut the other way. Steven Pinker and others have argued that evolution gave us competing drives rather than a single override switch.
The honest summary from that field would probably be: the drive is real, the temptation under those conditions is intense, and most of the forces keeping men faithful are social and psychological rather than biological.
A study published in the British Medical Journal using data from the National Social Life, Health, and Aging Project found that among men aged 75 to 85, about 39 percent remained sexually active. That means a majority had stopped by that age range, suggesting the median cessation falls somewhere before 75. Other research points to the late 60s as the period when frequency drops sharply for many men, though a meaningful minority remain active well into their 80s.
The range is enormous. Health is the dominant factor, more than age itself. Cardiovascular disease, diabetes, obesity, testosterone decline, and medication side effects all suppress sexual activity significantly. A healthy 75-year-old man may have a more active sex life than an unhealthy 60-year-old.
Relationship status matters too. Men without partners stop having sex at higher rates than men in relationships, which reflects opportunity as much as desire.
Charles Taylor‘s distinction between the buffered and porous selves comes from A Secular Age, where he contrasts the pre-modern porous self with the modern buffered self. It adds something genuinely interesting to the adultery question.
The porous self of pre-modern culture had no firm boundary between inside and outside. Spirits, forces, social obligations, and divine commands penetrated the self directly. A man in that world experienced his obligations to wife, family, and God as external forces that inhabited him, not merely rules he had chosen to follow. Violation carried a weight that was almost physical, something closer to pollution or contamination than to rule-breaking. The social and sacred world pressed in on him constantly.
The buffered self that Taylor associates with modernity has erected a wall. The modern individual experiences himself as the author of his own meaning, protected from external forces by a sense of inner sovereignty. Moral commitments become choices rather than constraints imposed from outside. Religion, social expectation, and even love become things the self ratifies rather than forces the self submits to.
Applied to adultery, this suggests something worth taking seriously. The buffered man experiences temptation differently. He does not feel the weight of violated sacred order pressing in on him. He reasons about consequences, calculates risk, consults his preferences. The question becomes not “what kind of cosmos am I violating” but “what do I actually want and what will it cost me.” That is a much lighter set of restraints.
Taylor would not say the buffered self is simply more selfish. But he might say it is more alone with its desires, less held in place by forces larger than itself. A porous man in a religious community with a thick sense of honor and sacred obligation carries the community inside him. The buffered man has to generate his own reasons to resist, and that is a harder thing to sustain when a beautiful young woman is in the room.
