Paraphilia: One of several complex psychiatric disorders that are manifested as deviant sexual behavior. For example, in men the most common forms are pedophilia (sexual behavior or attraction toward children) and exhibitionism (exposing one's body in public setting). Other paraphilias include compulsive sexual behavior (nymphomania and priapism), sadism, masochism, fetishism, bestiality, and necrophilia. Treatment may include cognitive behavioral therapy, psychotherapy, behavior modification, antidepressant medications, and medications that alter hormone production, particularly of testosterone. However, the cause and treatment of paraphilias are poorly understood, and treatment is rarely effective. In addition, many professionals prefer not to pathologize sexual behavior that involves only willing adults, even if the behavior might be deemed deviant in mainstream society. In cases where the behavior is potentially criminal, as in pedophilia, treatment is usually offered within the penal system.
