"Hundreds of Britons are being urged to attend what is being branded as Europe’s first “Masturbate-a-thon,” a leading British reproductive healthcare charity said Friday. Marie Stopes International, which is hosting the event with HIV/AIDS charity the Terrence Higgins Trust, said it expected up to 200 people to attend the sponsored masturbation session in Clerkenwell, central London, Saturday.

Participants, who have to be over 18, can bring any aids they need and can take part in four different rooms — a comfort area, a mixed area, along with men and women only areas. However, the rules on the event’s website states there can be no touching of other participants nor are people allowed to fake orgasms. “The amount you raise will be determined by how many minutes you masturbate and/or how many orgasms you achieve,” the website said."
