Naturism in the United States
Naturism in the United States is the practice of social nudity as a lifestyle that seeks an alternative to the majority view of American society that considers nakedness and sexuality to be taboo based upon the legacy of Puritan and Victorian attitudes. Enthusiasm for naturism began in the late 1920s with the establishment of members-only communities where naturists could gather to socialize and enjoy recreation without clothing in an environment that was no more sexual than that experienced while clothed.
