Compulsive sexual behavior is sometimes called hypersexuality, hypersexual disorder, nymphomania or sexual addiction. It's an obsession with sexual thoughts, urges or behaviors that may cause you distress or that negatively affects your health, job, relationships or other parts of your life. Treatment for compulsive sexual behavior typically involves Psychotherapy (Psychodynamic psychotherapy and Cognitive behavioral therapy), medications and self-help groups. A primary goal of treatment is to help you manage urges and reduce excessive behaviors while maintaining healthy sexual activities. Impulsive-compulsive sexual behavior is a little studied clinical phenomenon which affects approximately 5% to 6% of the population. In the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-Text Revision, it is classified as an impulse control disorder not otherwise specified or a sexual disorder not otherwise specified. It may be placed in a possible new category in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition called substance and behavioral addictions. A new study will be started with brain-wave activity to better understand the nature of compulsive sexual behavior.
