Those who like to watch, those who like to be watched...those who get off exposing their naked flesh in public, and those who get a cheap thrill form seeing what should not be seen. Exhibitionism has been called by some scientists as "sexual advertising." One might say we live in a world of voyeurism--the need to watch and see foul things, from sex and violence on TV, to fights and executions, to the car crash we all slow down to look at, causing traffic jams and more accidents. In clinical psychology voyeurism is the sexual interest in or practice of spying on people engaged in intimate behaviors, such as undressing, sexual activity, or other activity usually considered to be of a private nature. In popular imagination the term is used in a more general sense to refer to someone who habitually observes others without their knowledge, and there is no necessary implication of any sexual interest. In these ten case studies, Dr. Mundinger-Klow examines and interviews five self-called exhibitionists and five self-labeled voyeurs to understand the compulsion of both, and how each one needs the other to perform the symbiotic sexual relationship.
