In this episode of Infrequently Asked Questions, Atlas Obscura goes behind the scenes and back in time with Dr. Carol Queen, sexologist and curator of the Good Vibrations Antique Vibrator Museum in San Francisco, in order to answer questions like: How have vibrators been marketed to women throughout history? How did the museum acquire the vibrators in the collection? Which vibrator in the collection has the most novel design?
