sexual addiction
a problematic sexual behavior, such as a paraphilia or hypersexuality, regarded as a form of addiction similar to drug addiction. The defining features of a sexual addiction include sexual behavior that is out of control, that has severely negative consequences, and that the person is unable to stop despite a wish to do so. Other features include persistence in high-risk, self-destructive behavior; spending large amounts of time in sexual activity or fantasy; neglect of social, occupational, or other activities; and mood changes associated with sexual activity.
