Porn addiction is a widely used phrase, but it is not the name of a standalone diagnosis in the ICD-11. The loss of control or unwanted consequences a person is trying to describe may still be real: researchers often use problematic pornography use (PPU), while a clinician may assess the broader diagnosis of compulsive sexual behaviour disorder (CSBD).
The terms overlap, but they do not mean the same thing. Knowing the difference can help you describe what is happening without turning a concern into a self-diagnosis.
Evidence strength: stronger for the ICD-11 classification of CSBD; developing for how PPU is defined, measured and how common it is; early for what causes it.
Is porn addiction real?
There is no simple yes-or-no answer because the question mixes an experience with a diagnostic label.
What we know: people can experience repeated difficulty controlling porn use and continue despite consequences. Those concerns deserve to be taken seriously. One reported pattern is continuing even when enjoyment has faded. The World Health Organization recognizes CSBD, a broader disorder that can involve pornography, within the ICD-11 grouping of impulse-control disorders. It does not recognize a separate condition named “porn addiction.” See the WHO clinical manual.
What we do not know: whether every persistent porn problem is best understood through an addiction model. The ICD-11 working group placed CSBD among impulse-control disorders because the evidence was not yet sufficient to classify it with disorders due to addictive behaviours. Kraus and colleagues explain that decision.
You do not need to win that classification debate before you can address lost time, broken agreements, or repeated failed attempts to change.
What is considered a porn addiction?
There is no agreed threshold: no number of hours, days or videos that turns use into an addiction. What clinicians and researchers look at is a pattern. That means difficulty controlling use, repeated failed attempts to cut down, porn crowding out other parts of life, and carrying on despite harm, with distress or impairment that lasts months rather than one bad week. Kraus and colleagues describe the ICD-11 requirements. How often you watch is not, on its own, the test.
The signs of porn addiction goes through each of those patterns, and the self-check helps you apply them to your own life.
What does problematic pornography use mean?
Problematic pornography use is a research term for porn use associated with impaired control, distress, or unwanted consequences. It is more specific to pornography than CSBD, but it is not one universally agreed diagnosis. The 2026 measurement review shows how definitions and instruments still vary.
That distinction matters when you see a study or take an online porn addiction test. A 2026 systematic review found 24 different PPU measures across 47 studies. None could be unequivocally recommended, although four were identified as promising. A score can support research or a clinical conversation; it cannot diagnose you by itself. Read the measurement review.
PPU is also not a synonym for frequent use. Frequency can describe how often something happens. It cannot, on its own, tell you whether you have lost control or whether the pattern is impairing your life.
Is porn use disorder a formal diagnosis?
“Porn use disorder” or “pornography-use disorder” appears in some research and clinical writing, but the ICD-11 does not list it as a separate diagnosis. A paper using that phrase may be studying a proposed construct, a screening threshold, or porn use considered within CSBD.
The name therefore does not tell you how participants were assessed. Check whether a study used a questionnaire, a clinical interview, or formal diagnostic requirements—and whether it examined pornography alone or a broader sexual-behaviour pattern.
What is compulsive sexual behaviour disorder?
CSBD is the clinical term in ICD-11. It describes a persistent failure to control intense, repetitive sexual impulses or urges that results in repetitive sexual behaviour and marked distress or impairment over an extended period. The pattern may involve pornography, masturbation, partnered sexual behaviour, or more than one activity. Read the ICD-11 explanation.
High sexual interest alone is not CSBD. Nor should the diagnosis be based only on distress arising from moral disapproval. A clinician also considers other health conditions, medication or substance effects, mood episodes, mental health, sexual health, consent, and the person’s wider circumstances. The sexual-medicine review describes that broader assessment.
How are porn addiction, PPU, and CSBD different?
| Term | Where it is used | A formal diagnosis? | What it cannot tell you |
|---|---|---|---|
| Porn addiction | Everyday language, some services, and some research | Not a standalone ICD-11 diagnosis | Whether an addiction model or any diagnosis fits |
| Problematic pornography use (PPU) | Research and some clinical discussions | Not one universally defined diagnosis | Whether a screen-positive person has CSBD |
| Porn use disorder | Some research and proposed clinical language | Not a separate ICD-11 diagnosis | How the term was measured in a particular paper |
| Compulsive sexual behaviour disorder (CSBD) | ICD-11 and qualified clinical assessment | Yes, as a broader impulse-control disorder | Whether porn use alone meets the requirements |
What causes porn addiction?
There is no single known cause. Most of what researchers say about causes comes from models and from studies that measure people at one point in time, so they show associations rather than proof. Three threads come up repeatedly.
Cues, craving and self-control. The I-PACE model, a framework for behavioural addictions that explicitly includes compulsive sexual behaviour, proposes that problems develop from an interaction between a person’s predispositions, how they react to cues and stress, and executive functions such as inhibitory control. Over time, strong craving in response to cues, combined with weaker inhibitory control, may turn a behaviour into a habit. It is a framework to test, not a proven mechanism. Brand and colleagues. Why porn in particular can be so hard to put down is covered in porn and dopamine.
What porn is being used for. In three samples used to build a scale of reasons for watching, using porn for stress reduction, emotional distraction or suppression, boredom avoidance, fantasy and sexual pleasure were each weakly to moderately associated with problematic use. Bőthe and colleagues. When porn becomes the main way to handle difficult feelings, those feelings are part of the picture: see porn as a way to cope and ADHD and porn.
Values and the feeling of being addicted. Some people feel addicted mainly because watching clashes with their moral or religious values. Grubbs and colleagues propose that this moral incongruence explains many self-reported porn problems. Read the review. Moral conflict and loss of control can exist together, and a good assessment separates them. If guilt is the loudest part, see guilt after watching porn.
How many people have a porn problem?
Estimates depend heavily on the questionnaire. In the International Sex Survey of 82,243 people in 42 countries, between 3.2% and 16.6% screened as at risk of problematic use, depending on the tool, and only 4% to 10% of them had ever sought treatment. Bőthe and colleagues, 2024. On a broader ICD-11-based measure, 4.8% of the same survey were at high risk of compulsive sexual behaviour disorder. Bőthe and colleagues, 2023.
In a nationally representative sample of 2,075 US adult internet users, about 11% of men and 3% of women agreed at least somewhat that they were addicted to pornography. That feeling was linked with being male, younger, more religious, more morally conflicted about porn, and watching more. Grubbs, Kraus and Perry.
Screening above a cut-off is not a diagnosis. For how common porn use itself is, see do all men watch porn?
What should you call your own experience?
Use the words that help you begin, then describe events rather than trying to prove a label: “I planned to stop, continued for another hour, and missed sleep” gives a professional more useful information than a score or identity alone.
If you are still deciding whether the pattern is a problem, look at the signs of porn addiction. If repeated efforts are not changing it, or it is affecting daily life, relationships, or sexual wellbeing, a qualified professional can assess the whole picture. Our guide to porn addiction treatment explains what that conversation can include.
