F66: Other sexual disorders

F66 refers to Other sexual disorders, a group of behavioral and psychological conditions that impact personality development, impulse control, identity, and interpersonal relationships. These diagnoses are used to describe enduring patterns of behavior and internal experience that differ markedly from cultural expectations.

Symptoms

• Rigid or maladaptive behavior patterns – Seen in F60 personality disorders
• Failure to resist impulses – Common in F63 disorders like kleptomania or pyromania
• Distress about one’s gender – Describes F64 gender identity disorders
• Sexual urges involving atypical objects or situations – Found in F65 paraphilias
• Sexual orientation conflicts or social stress – Linked to F66 disorders
• Factitious behaviors or exaggerated symptoms – Associated with F68
• Unclassified personality/behavior traits – Coded under F69

Diagnosis

Diagnosis of Other sexual disorders involves clinical interviews, personality inventories (like MMPI or SCID), behavioral observation, and in some cases, collateral information from family or caregivers. Duration, functional impact, and distress level are key criteria for diagnosis.
