Managing a "disorder of desire" typically involves staying at a treatment facility for four to seven months. During the first couple of weeks, patients undergo extensive testing to determine their arousal and behavioral patterns, and to find out if there is a physical explanation for the behavior - a brain tumor, for example. Patients participate in three group psychotherapy sessions a day and meet one-on-one with therapists two to three times a week. They also take medication, usually antidepressants, which have the side effect of curbing sexual desire.
