You might equate an event called the Masturbate-a-Thon with “only in San Francisco.” But you'd be wrong. San Francisco was the site of the first one, but similar events have occurred in Portland, London, and Copenhagen. According to organizer Carol Queen, the idea for the event came after U.S. Surgeon General Joycelyn Elders was fired in 1994 for acknowledging that masturbation is part of human sexuality, and that it might be taught to young people as a way of preventing riskier sexual activity. (That Elders was fired by Democrat Bill Clinton says a lot about how much we as a nation are still hung up on the issue.)
At Sunday's Masturbate-a-Thon at the Center for Sex and Culture, people can sponsor themselves for $40 or seek others who'll pledge money. The longer you can go without reaching orgasm, the more you bring in. And yes, there are records for this sort of thing.
