San Francisco's Center for Sex and Culture played host on Saturday to the city's annual "Masturbate-a-thon," an event its organizers said could draw up to 120 people from across the United States aiming to have a good time with themselves.
The event was organized to help raise funds for the center, and, according to its organizer, provide an outlet for safe sex for those who enjoy pleasuring themselves in a semi-public setting.
Carol Queen, director of the center, acknowledged that the event is unusual -- even by San Francisco's standards.
Ummm...if you read on there's mention of a webcast...
Sounds like the beginning of History of the World Part I.
