The Masturbate-a-Thon was built up by Good Vibrations, which encouraged other modern sex-toy businesses—such as Babeland; A Woman's Touch, in Madison, Wisconsin; Toronto's Come As You Are; and Boston's Grand Opening—to hold events coinciding with "masturbation month" (May in the United States).
Good Vibrations, a company specializing in adult products, initiated the Masturbate-a-Thon event and inspired other companies like Babeland, A Woman's Touch, Come As You Are, and Grand Opening to organize events during "masturbation month" (May) in the United States.
