Naturism (also called nudism) is a term used by individuals or groups who believe being nude with other people has many benefits, and should be allowed or promoted. Seeing members of the opposite sex allows people to learn that nudity is not just about sex. Seeing a variety of bodies of all types produces a more realistic and positive self-image. Some naturists want to be nude in places to which only other naturists have access, such as camp grounds or resorts. Other want areas of public property such as swimming beaches to be designated "clothing optional" without limiting access to non-naturists. Individuals who practice nudity in the home or other places where only family or friend are present are not generally thought of as naturists. The movement developed in Europe, and European countries (especially those in the north of Europe), are generally more tolerant towards nudity in public.
