A sex museum is a museum that displays erotic art, historical sexual aids, and documents on the history of erotica. They were popular in Europe at the end of the 1960s and during the 1970s, the era of the sexual revolution. Since the 1990s, these museums have tended to be designated erotic museums or erotic art museums rather than sex museums.
