Is Porn Bad for You? What the Research Says About Mind, Body, and Marriage

Oct 18, 2026

Many of the Christian men I work with have spent years caught between two answers to one question: is porn bad for you? Their church and their own conscience said yes. Nearly everything else, from podcasts and articles to the coworker who shrugs it off, said it’s normal and even healthy, and that the only real harm comes from the guilt religious people attach to it.

If you’ve half believed both answers, you aren’t confused. You’re paying attention, and you deserve a straight answer.

Here’s mine. Yes. Jesus said looking with lust is adultery in the heart, and no amount of research changes that. Even one look can scar a man for life. I know plenty of men who saw pornography only once as boys and came away believing they were unworthy, and that belief shaped their weaknesses for decades. In more than 4,000 one-on-one sessions, I’ve watched what this habit produces in the places a man cares about most: his marriage, his focus, his faith, and his freedom to choose.

Jesus gave a simple test for telling the real thing from what only looks good: “Wherefore by their fruits ye shall know them” (Matthew 7:20). He was speaking about prophets, but the same test works on a habit. Let’s use it.

Is Watching Porn Normal, and Does That Make It Healthy?

It’s certainly common, and if you’re struggling, you are far from alone. In a 2021 national survey of couples by Brigham Young University’s Wheatley Institute, roughly three in four married men reported at least some current pornography use. In 2024, Barna Group and Pure Desire Ministries reported that 61% of U.S. adults say they view pornography, and 44% believe “watching pornography has little impact on the other aspects of an individual’s life.”

It starts young. In a study of 813 students at six U.S. colleges, 87% of the young men reported using pornography, and about two-thirds said viewing it was acceptable. Those students are now in midlife, close to the age of many men reading this.

Feeling uneasy anyway doesn’t make you strange. In surveys published by Pew Research Center in 2026, 52% of U.S. adults said viewing pornography is morally wrong.

But is watching porn healthy just because it’s common? Those are different claims. Is it natural to feel the pull? Yes. Is it common? Very. Is it still a problem? Yes.

I regularly hear from people who think my work does harm. I opened Section One of my book with one of those messages, exactly as it came to me:

“Human sexuality is normal and healthy, it's the shame you peddle that is actually harmful. … You’re a predatory leech sucking victims dry.”

Here is what I wrote right after it:

“Truth makes you free. Lies make you stuck. Period.”

Sexuality is a good gift from God, and shame has never set anyone free. If guilt and fear could end this habit, the men I work with would have been free years ago. They’ve had plenty of both. Where I part ways with that message is the leap from sexuality being good to everything done with it being good for you. Hunger is natural and good, too, and a man can still feed it with things that make him sick. The real question is what this habit is producing in your life.

Is Porn Bad for You? Six Places to Look for the Fruit

The test itself is plain enough for any farmer:

“Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?” (Matthew 7:16).

One thing to know before we look at the research: most studies in this area hand people a short survey and ask what they think. That can only measure what a man perceives about himself in a few minutes, and most of us answer in ways that make us look better. Keep that in mind as you read.

Your marriage and your satisfaction

In 2017, researchers gathered 50 studies with more than 50,000 people in 10 countries and looked at them all together. Their question was simple: do people who watch more pornography feel happier or less happy with their sex lives and their relationships? For men, the answer was less happy. The more pornography a man used, the less satisfied he tended to be with his partner and his relationship.

Another study asked 430 people in relationships to write down, in their own words, what effect pornography had on their relationship. The most common answer was “no negative effects.” Notice the word that study measured: what people perceive. It only captured what came to mind in a quick survey.

Every man I’ve ever talked with who thought porn was harmless ended up admitting more once we went deeper. It made him objectify women more. He needed explicit material to get aroused. He couldn’t stay present during intimacy with his wife. His self-esteem sank because he couldn’t control his urges. Back in the Wheatley survey, one in four men said they actively hide their viewing from their partner. A man doesn’t hide what he believes is harmless. In my office, the cost rarely arrives as one dramatic blowup. It arrives as distance, and we often work with the betrayed wives who feel it first.

Escalation and the pull toward more

A 2024 study of about 2,300 men in the U.S. and U.K. looked at the ways pornography use grows. The men answered questions about needing more over time, bingeing, jumping from video to video, and moving toward more intense material. The researchers found that needing more sat at the center of it all. It was the piece most tied to every other pattern and to men losing control of their use.

At Cambridge, a smaller study showed men sexual pictures again and again while scanning their brains. Men with compulsive sexual habits were pulled harder toward new pictures than other men were. And as the same pictures repeated, their brains responded less and less, faster than other men’s brains did. In plain terms, the same thing stopped being enough. (I’ve written more about the brain side in our post on the cues behind the habit.) Men describe the same drift in their own words: private lines they once drew, moved one at a time.

Mood and the false relief

Many men use pornography for temporary pleasure they want to pretend is relief, but the false relief is quickly revealed to be a deceiver. In a survey of 434 men, the men who used online sexual activity to change their mood were more likely to have problems with it. What follows the false relief is always heavier than what came before.

In my book, I list what porn does to a man, and most men don’t see it until it’s named: “Numbing you out from feeling normal emotions, Distancing you from meaningful relationships, Creating social anxiety, Creating damaging self-talk, Creating guilt, Creating shame, Creating anger, Creating fear of judgment, Creating self-criticism, Creating sensations of weakness, More feelings that you’re not enough.” The low mood after a slip then becomes the next reason to reach for it again, and the cycle of shame and secrecy starts over.

Sexual function

In an international survey of 3,419 men ages 18 to 35, about one in five of the sexually active men had some degree of trouble with erections. The men with more problematic pornography use were more likely to have that trouble. A survey at a Navy urology clinic found that erectile problems were far more common among men who preferred pornography to sex with a partner.

Some erectile problems may have physical roots, such as heart and blood vessel disease or diabetes. But poor blood flow is a symptom, not a root. Something tells those blood vessels to tighten, and the mind is very powerful at doing exactly that. Stress, fear of failing, and years of training arousal to a screen all live in the mind, and that is where we work.

Attention, time, and presence at home

Researchers followed 123 college students for four weeks. They offered each student a choice: a small reward now, or a bigger reward later. The students who used more pornography at the start were more likely, four weeks later, to grab the small reward now. Pornography trains a man to want quick pleasure over the things worth waiting for.

I call the rest of the cost brain calories: the energy spent guarding a secret and bracing for the next urge. A man can stand on the sideline at his daughter’s game, cheering at all the right moments, while half his attention is on what he’s hiding. When the pattern finally changes, the attention that comes back is something clients bring up again and again.

Conscience and faith

Two studies of more than 2,200 people found that people who felt hooked on internet pornography struggled more with God and their faith. A year later, that feeling of being hooked still predicted more spiritual struggle.

The fruit in my office looks the same. Men tell me prayer has started to feel like talking to a wall, and Sunday has started to feel like a performance. That distance has nothing to do with God’s willingness. It has everything to do with what a secret does to a man’s confidence before Him.

Paul’s Two Questions: Is Watching Porn Bad, or Just Allowed?

For years, the question running in the background has probably been “Is this allowed?” or “How much is too much?” Paul faced a version of the same argument in Corinth, and he moved the conversation somewhere more useful:

“All things are lawful unto me, but all things are not expedient: all things are lawful for me, but I will not be brought under the power of any” (1 Corinthians 6:12).

The Greek word translated “expedient” means to help, to be profitable, to be better for you (Strong’s G4851). So Paul’s test has two parts. Is this doing me good? Is it starting to have power over me? Four chapters later he said it again: “All things are lawful for me, but all things are not expedient: all things are lawful for me, but all things edify not” (1 Corinthians 10:23).

Pornography fails both tests. It builds nothing up, and it brings a man under its power. Ask yourself about your own last ten years. What has this produced in your marriage and your prayers? If you decided tonight to be done, could you simply be done? Your answers are worth bringing to a conversation with us.

What Another Decade Would Cost

Paul gave us the law of the harvest:

“Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap. For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting” (Galatians 6:7-8).

In my book I put it this way: “The natural and eternal law of the harvest says one cannot sow lust, infidelity, disloyalty, and lack of control, and reap anything other than lust, infidelity, disloyalty, and lack of control.”

Another ten years, for many men reading this, is most of the time their kids have left at home. It’s also the stretch when a marriage either grows closer or settles into polite distance.

The hopeful half of that passage gets skipped too often. A man who sows differently reaps differently. If willpower kept failing you, it wasn’t because you’re weak. Willpower doesn’t work, because the pattern lives deeper than the behavior, in beliefs about who you are and what you need. It’s not necessarily a character flaw. Often it’s an identity your subconscious learned, sometimes from a single moment in childhood. One client went into trance and found exactly that. From my book:

“He came across a picture of a nude woman and he immediately had all the confused, excited feelings that come with that experience. He stuffed the picture in his pocket because part of him really wanted to look at it, but the other part of him knew he needed to hide it for later when he could look at it privately. His whole porn problem ended up being ‘fear of being caught.’ When he released that 7-year-old mentality, he began to have control again.”

What was learned can be relearned. Michael Bernard Beckwith, whose teaching on vision has shaped my own thinking, put the choice plainly in a 2024 conversation: “Do I want to grow or do I want to just manage problems?” Most of the men who reach my office have spent ten or twenty years managing this one. Tim, 30, had carried it for 20 years. In his words:

“I wanted to just nuke and obliterate it, no more day by day approach. That is exactly what happened.” (Tim, 30, after 20 years, one session)

Questions Men Ask About Porn and Their Health

Is watching porn unhealthy if it’s only once in a while?

Yes. My view comes from the Sermon on the Mount: “But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart” (Matthew 5:28). It’s a sin, and “For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord” (Romans 6:23). Of the holy city, John wrote, “And there shall in no wise enter into it any thing that defileth, neither whatsoever worketh abomination, or maketh a lie: but they which are written in the Lamb’s book of life” (Revelation 21:27). So stop wondering whether once in a while is a problem. Eliminate it and be done with it. It’s unjustifiable in any form. As I wrote in my book about men who told me they only look every few months now: “Let me assure you, there is nothing acceptable to God about that, nor is it acceptable to most spouses. If you think about it for two seconds, you know it’s not acceptable to you, either.”

What are the side effects of watching porn?

Many men say they notice none. The key word is notice. When pressed, they report massive negative effects, if nothing else the secrecy and the loss of control. Research has tied more frequent or problematic use to lower relationship and sexual satisfaction in men, a pull toward more or newer material, a stronger preference for quick rewards over lasting ones, and more erectile difficulty with a partner. Whether a man’s use is frequent or problematic, both are damaging.

What are the consequences of porn addiction?

Researchers argue over the word addiction, but it isn’t debated in my mind. Addiction implies you depend on something to be happy and can’t change it. We redefine it as a compulsive string of bad habits that can easily be changed. Whatever you call it, the consequences men describe to me are remarkably similar: secrecy in a marriage, lost hours and focus, escalation, sexual difficulty, strain in their walk with God, and an exhausting cycle of promising and failing. The effects of porn addiction build slowly, which is part of why they’re so easy to underestimate.

Can a man really change after 20 years of this?

Yes, and fast. The subconscious doesn’t deal in time or magnitude. It doesn’t care how big the problem is or how long it has been there. It can change at the speed of thought. One client put it this way in a review: “Common sense that is NOT so common. Gets to the core of the matter for practical solutions that go beyond the surface. After years of trying everything, this was the first thing that actually worked.” (Robert M., Google review, Lehi, Utah)

Your Next Ten Years Can Look Different

Jesus said, “Again, the kingdom of heaven is like unto treasure hid in a field; the which when a man hath found, he hideth, and for joy thereof goeth and selleth all that he hath, and buyeth that field” (Matthew 13:44).

Notice why the man lets everything else go: “for joy thereof.” In my book I wrote, “I’m not the treasure, and I’m not the pearl, nor is hypnotherapy. The treasure and the pearl is your holiness.” When a man sees that clearly, giving up the old habit stops feeling like loss.

Christ is the first and best help, always. What we offer is a focus tool that works alongside prayer, never in place of it. Our clinical hypnotherapy sessions are private and one-on-one, in person in Utah or by video anywhere. The work aims beneath the behavior, at the belief about who you are that has kept a compulsive pornography habit alive for years. When that belief changes, a man no longer has to spend his life standing guard.

One session is often all it takes. In my book I describe a man who had attended a support group for ten years and even mentored others in it, yet still had a severe habit: “I saw him once and that’s all it took to fix his problem.” Results like his are typical, not rare. We have a 95% recovery rate in as little as 1-3 sessions, guaranteed: the program is backed by a money-back guarantee.

When you’re ready, schedule your free, confidential call. You’ll talk with someone on our team, and your privacy is protected from the first conversation to the last. Ask the hard questions, including whether this fits your faith, and take whatever time you need to decide. No one will pressure you. It isn’t too late to plant something different.
