The ICD-11 impulse-control diagnosis based on persistent impaired control and significant impact.
Back to the glossaryClinical literacy
Compulsive sexual behaviour disorder
An ICD-11 impulse-control disorder involving a persistent failure to control intense, repetitive sexual impulses or urges, resulting in repetitive behaviour and marked distress or significant impairment over an extended period.
Clinical literacy
In brief
Persistent impaired control and significant impact—not high desire or moral conflict alone.
CSBD is not diagnosed from high libido, frequent sex, masturbation, pornography use, kink, infidelity or moral discomfort alone. The core is persistent impaired control, such as repeated unsuccessful attempts to reduce behaviour, neglect of responsibilities, continuation despite adverse consequences or continuation with little satisfaction, usually for six months or more.
Frequent or intense sexual interest without the required impaired control and distress or impairment.
Conflict between behaviour and personal or religious values; distress from this alone is insufficient for CSBD.
A popular and contested framework that is not automatically equivalent to the ICD-11 diagnosis.
Required pattern
ICD-11 describes a persistent failure to control repetitive impulses or urges leading to behaviour that becomes central, resists repeated reduction attempts, continues despite consequences or yields little satisfaction.
The pattern occurs over an extended period and produces marked distress or significant impairment in important functioning.
Boundaries with normality
High sexual interest or activity without impaired control and significant impact should not be diagnosed. Frequency thresholds alone are specifically inadequate.
Distress entirely due to moral judgement or others' disapproval does not satisfy the diagnostic requirement, though that distress may still deserve compassionate support.
Differential assessment
A clinician considers mood episodes, neurological or medical conditions, medicines and substances that may better explain disinhibition. They also assess trauma, mental health, sexual function and relationship context.
CSBD is not a label for consensual non-monogamy, kink or a partner's objection to ordinary desire. Harmful or illegal behaviour must be addressed directly rather than explained away by diagnosis.
Care and accountability
Treatment is individual and may involve psychological approaches, management of co-occurring conditions and selected specialist medicine. Evidence and service availability vary.
Recovery goals focus on control, wellbeing, safety and chosen values rather than compulsory abstinence from all sexuality. A diagnosis never removes responsibility for consent or harm.
Non-graphic examples
What the umbrella may include
- Repeatedly failing to reduce a behaviour despite serious consequences.
- Having high libido with intact control and no impairment.
- Feeling moral guilt without evidence of impaired control.
- Reviewing a possible manic episode before diagnosis.
- Seeking specialist help while remaining accountable for consent.
