Mindset of a cheating man

The mindset of a cheating man: what you need to know about infidelity in marriage

Men usually cheat in a delusional fog.

They believe that cheating can bring them better sex, lift their spirits, and boost their sagging self-esteem.

And a few of them still hope to find “true love”.

No one wants to know that very often, cheating ends up wrecking multiple relationships and actually eroding a man’s confidence and sense of self.

We can’t say much about infidelity before defining it.

Let’s define what is infidelity.

Infidelity definition

Infidelity is the act or fact of having a romantic or sexual relationship with someone other than one’s husband, wife, or partner.

/Merriam-Webster Dictionary/


Sexual Infidelity vs. Emotional Infidelity

Sexual infidelity is usually understood as a violation of the expectation of your sexual exclusivity and can be as minor as a kiss or as significant as sexual intercourse.

Experts and researchers usually define infidelity as a major sexual transgression, requiring a minimum of genital contact.

Emotional infidelity implies an intense emotional bond with a fair amount of sexual tension and desire.

Often the most powerful affairs are those that are both emotional and sexual.

Studies have repeatedly shown that women perceive emotional infidelity to be near as threatening to their relationships as physical affairs.

Men, meanwhile, tend to worry more about sexual betrayals.

Infidelity in marriage: causes

Infidelity can come from a variety of social circumstances and situations.

I have met some married guys who cheat despite the fact that they are happy with their spouses.

In surveys over half of the cheating men reported that they were perfectly content with their long-term relationships and cheated despite their satisfaction.

So who can cheat? Anyone! Anytime! Anyplace!

Causes of Cheating

Dr. Kenneth Rosenberg has found three main factors that determine the mindset of a cheating man:

  • Brain—the neurological structures and chemistry that evolution gave you
  • Psychology—the mind that you’ve developed through formative experiences that imprint certain ways of thinking about the world, your place in it, and how you think about your sexual/romantic self
  • Culture -the environment, with its various messages about sex, love, and adultery, which shape opinions and opportunities for infidelity.

Studies say, that nearly 50 percent of what differentiates cheaters from noncheaters has to do with biological differences in their brain chemicals.

This means that more than half of what pushes a man to cheat has to do with both one’s environment and one’s psychology.

The most significant environmental cause is the fact that man can cheat.

The easier it is to do, the more likely they will do it.

Cheating is not confined to sleazy guys.

Under the right circumstances, it is very easy to turn lustful thoughts into desperate actions.

As we know from studies of chemical addictions, there are several environmental factors that make bad behaviors more doable. Professionals refer to these as the three A’s. If bad behavior is affordable, accessible, and anonymous, men are more likely to do it.

Psychological facts about the mindset of a cheating man

When it comes to the psychology of cheaters, the biggest factor driving them to stray is the feeling that they’re entitled to or deserve to cheat. Research and clinical experience have identified certain personality traits to be associated with this feeling:

1. Narcissism—feeling self-entitled and putting one’s needs first
2. Lacking empathy—not being able to put oneself in another’s shoes

3. Grandiosity—overestimating one’s abilities, especially one’s sexual prowess, and needing validation for one’s abilities as a lover
4. Being impulsive—making important decisions, with major consequences, on the fly
5. Being a novelty or thrill-seeker—we will devote two chapters to cheaters seeking novel experiences
6. Having an avoidant attachment style—fearing commitment
7. Being self-destructive or masochistic—a hard-to-grasp psychological

My husband cheated and I can’t get over it 

What Surveys tell us about  infidelity in marriage

Infidelity is often cited as the major cause of divorces in the United States, blamed for untold numbers of suicides, and understood to be the root of much unhappiness. But for those who want to stay married after a relationship transgression, it’s helpful to know that there is a silver lining to the statistics.

Your relationship does not need to end if you can figure out how to communicate and collaborate after the discovery of infidelity.


Although infidelity may be the event that causes a traumatic rupture to the relationship and can throw an unsuspecting partner into despair, it is not the act of infidelity per se that destroys the couple.

Remember, relationships end when you fail to communicate openly when you struggle with uncertainty about your relationship and lack the commitment to make your marriage work.

And when you are unable to bridge the gap after discovering that you have “grown apart.”

These are the issues that prevent repair and reconciliation after the discovery of affairs, and acknowledging these particular issues is the first step toward resolving them.

There are plenty of infidelity stats

Here are some key points.

In 2015 the polling site YouGov surveyed about a thousand Americans and reported that 20 percent of men admitted to cheating on their wives.

 27 percent of women said they have taken back a partner after discovering infidelity.

According to a survey,  35 percent of women were upset by sexual infidelity and 46 percent of women were upset by emotional infidelity.

Interesting facts about cheating

European men and women are more likely to cheat than Americans.

Frequent-flyer business travelers are more likely to cheat than those who don’t travel for work.

In fact, given that summertime is the peak season for travel, it also becomes a time for new lovers, with the summer months being the peak period for cheating.

Infidelity is not sanctioned by society:

90 percent of people consider sexual infidelity immoral,

and 65 percent consider it unforgivable.


In the past male philandering was more acceptable.

Since the mid-1970s the General Social Survey of the National Opinion Research Center’s (NORC) Center for the Study of Politics and Society has been monitoring attitudes towards sexual behaviors (including infidelity) among a representative sample of nearly thirty-seven thousand Americans.

According to their most recent findings, which may contain the most scientific data about infidelity in marriage, the number of married men who have ever cheated has remained stable at around 20 percent since 1993.

The General Social Survey actually shows higher disapproval of infidelity today than in the 1970s.

Interesting fact –  For men over sixty cheating has increased since 1991 by 14 percent.

Among Dr. Kenneth Rosenberg’s male patients, the surprising reality is that the vast majority have cheated by the age of sixty.

He treats a fair number of middle-aged patients, between the ages of forty and sixty, which is precisely the age range when men are most likely to cheat.

What do cheating husbands think about their cheating?

They often minimize their dalliances, even with themselves.

They ignore the make-out session with the old flame at the high school reunion.

They don’t count the affair as cheating if the adulterous relationship turns into a second marriage.

They say it didn’t count because we were drunk.

They say strip clubs and naked women grinding on their genitals till orgasm didn’t count because they were just blowing off steam with the guys.

Or they say things like the now-famous words of our philandering former president who allegedly received oral sex, but did not have vaginal intercourse, “I did not have sexual relations with that woman!”

Life Circumstances That Lead to Cheating

Studies tell us there are associations between cheating and life situations.

There is conflicting data about the impact of age, with some surveys claiming forty-nine to be the peak age of male cheating, other studies claiming thirty-nine years of age for men.

Personally, I think the risk is more dependent on commonsense factors like how long a couple has been married, where they are in their careers and with raising children, what their health and hormonal levels are like at various ages, and what is happening to them and among their peers in their community at any particular phase in their life cycle.

Neuroscience and Infidelity

One of the more fascinating contributions to understanding sex comes from emerging studies in neuroscience. Many marriage and relationship experts don’t understand this biology very well, but nonetheless, apply the results from a few rat studies to humans and, as a result, exaggerate the findings.

Other experts, meanwhile, do the opposite: they ignore the studies and call them “uninteresting” because neuroscience is beyond their understanding.

Some people seem to find the idea that chemicals determine human behavior to be creepy and hate the notion that their motivations can be understood by a set of predictable chemical reactions occurring in the brain. But the new neuroscience of sex and monogamy is fascinating. It’s worth understanding.

Anatomy – is it destiny or not?

“Anatomy is destiny,” wrote Sigmund Freud in his 1912 paper on the nature of romantic love. Freud was a strong believer that gender determined our thoughts and desires. Now, more than a hundred years later, scientists have found evidence of the actual biological mechanisms that contribute to our sexual desires.

We are born with genetic factors that cause chemical changes and influence our sexual thoughts and behaviors.

A second and maybe even more interesting piece of new information is that not only do your genes influence your behavior, but also your behaviors and thoughts can actually change your genes and your brain.

We have feedback loops—interconnections between biology, psychology, and culture—and when we experience a certain successful pattern of behavior for getting sex, it can forge a pathway in our brain, creating a channel we travel over and over.

These paths become deeply ingrained in our gray matter (where our brain cells, or neurons, reside) and act as the favored patterns for our actions. Memories become physiologically locked in our minds through chemical reactions.

Like a path in an overgrown forest, how we think about, seek out, and ultimately find sex creates a biological imprint in our brains, and it becomes difficult to venture off the established way that has brought us so much pleasure.

Chemistry of Affair

Affairs are also about chemistry. In fact, most people would say that the physical chemistry of the affair is the most important element because there is little sharing of familial duties and less time for chitchat. No time for long dinners, quiet evenings on the couch after the kids are asleep, or social engagements with family or friends. An affair often centers around sex, leaving aside other typical romantic activities.

So, naturally, sexual affairs are more about sexual chemistry than long-term relationships are, right?

Imagination  and desire for an Affair

Absolutely not. In truth, affairs usually involve spending less time with an actual, real, live human and more time with the person that we’ve conjured up from our yearnings, our hopes, our fantasies and fears, and from what psychiatrists call our “internal representations” of another.

Affairs are actually built not in the bedroom, but in the mind. Concocted in our irrationally exuberant and sometimes desperate imaginings, affairs draw their power from deep wants and needs. Their magnetism has its roots in desire.

Boring sexual life

An average couple engages in sex for under six minutes. Men’s orgasms last for less than five seconds on average.

Sex lasts minutes. Orgasms last seconds. But men can maintain their fantasies for a lifetime.

Fantasy is the flame of passion.

Cause of infidelity in marriage: Looking for Desire

Desire has a way of getting us engaged, keeping us in a zonked-out zone, getting lost in lust and love, and, in some cases, blinding us to self-destructive choices.

Today psychology and medical professionals say that the desire phase, deeply rooted in the psyche and the most psychologically complex, is the most pivotal.

A cheating man is looking for a novelty

Novelty Creates Desire in the cheating man’s brain

The New Rat in the Cage

Newness is intoxicating, literally. In fact, the pursuit of novelty is one of the most basic, primitive desires, which has been demonstrated in a multitude of different species, including rats.

The New Rat in the Cage

Drop a male rat into a cage with a female rat who’s in heat, and the two will copulate repeatedly until sexual exhaustion. Drop a brand new rat into the cage and, despite the other rats’ exhaustion, both male and female rats will rally to resume mating activity with the new partner. The new rat in the cage gets all the attention, despite the original rat’s disinterest in any additional sex with the previous mate. This phenomenon (called the Coolidge effect after a joke about then-President Calvin Coolidge and his wife) is an ancient biological program aimed at seizing genetic opportunities, driven by a neurological mechanism whereby potent brain chemicals jolt a “sexually satiated” animal to continue to copulate. The appeal of a new mate over a pre-existing mate can be seen in both males and females up and down the phylogenetic spectrum, from beetles to primates.

Why do guys cheat even if they love you?

Many men stray despite having spouses whom they desire and with whom they often enjoy great sex lives. They stray despite the fact that they are already paired with a perfectly good woman.

And if and when they divorce, the wife they dismissed like yesterday’s bad news becomes someone’s new perfect find.

Some of the cheating husbands succumb to each new opportunity or, to put it more crudely, each new rat in the cage.

They’re forever seeking someone new. Affairs of the heart and journeys of sexual desire take over the reward centers of their brain, and new sex and love further cloud or subvert the decision-making abilities of their brain’s frontal lobes.

Forbidden fruit

One of the reasons a cheating husband finds romance so enticing is that it is secret and forbidden. In fact, the offense itself is part of the prank – at least until guilt arises. Sociologists have recognized that adrenaline makes the heart more loving.

Desire often has more to do with a man’s own feelings, his mental representations of another, and the context of a new encounter than with the desired woman herself.

When a cheating man meets a new lover, he says, “I don’t know—she just excites me in a way my wife just can’t. I just married the wrong woman!”

He ignores the adrenaline of this forbidden chance encounter, the uncertainty of her desire for him, the pulse of the new music, the exotic new cocktail he’d ordered, and the unseen corners at the darkened bar.

Instead, man attributes his desire to the new person.

He compares the new woman to his old wife.

Although a cheating husband might not realize it, the thrill of the new, fueled by the brain’s novelty-seeking chemicals, is making his heart grow fonder.

New reality creates new possibilities for cheating

Internet porn, orgies, threesomes, cybersex, BDSM, and novelty—these desires open up worlds of anticipation, lust, and fantasy. And they are often the longings that propel men toward infidelity.
