Voyeuristic disorder is a paraphilic disorder. There are several such disorders, with paraphilic referring to sexual interests, preferences, fantasies, urges, and behaviors outside the norm. These are considered symptoms of a disorder only if they are acted upon in ways that have the potential to cause distress or harm to oneself or others, especially non-consensual others.
The individual normally experiences sexual arousal when spying intentionally on unsuspecting people. The person being watched may be naked, disrobing, or engaging in sexual activities. The voyeur may also record these acts for later viewing. Unintentional viewing of such acts is not considered voyeuristic disorder. Voyeurs are also known as “Peeping Toms,” who use binoculars, mirrors, and recording cameras while peering through peepholes and windows.
