Voyeuristic transtorno is characterised by a sustained, focused and intense padrão of sexual arousal—as manifested by persistent sexual thoughts, fantasies, urges, or behaviours—that involves observing an unsuspecting individual who is naked, in the process of disrobing, or engaging in sexual activity. In addition, in order for Voyeuristic transtorno to be diagnosed, the individual must have acted on these thoughts, fantasies or urges or be markedly distressed by them. Voyeuristic transtorno specifically excludes consensual voyeuristic behaviours that occur com the consent of the person or persons being observed.
