Gratification disorder

Overview
Gratification disorder (also known as "infantile masturbation", despite occurring in children as old as 10, or sometimes benign idiopathic infantile dyskinesia) is a form of masturbatory behavior that has often been mistaken for epilepsy, abdominal pain, and paroxysmal dystonia or dyskinesia. Little research has been published regarding this early childhood condition. However, most pediatricians agree that masturbation is a normal and common behavior in young children and should be recognized as such. Failure to recognize this behavior can lead to unnecessary and invasive testing. Thus, it should be noted that the use of the word "disorder" is somewhat malapropos, as an inability to experience sexual gratification would constitute sexual aversion disorder.
