A reproductive charity is encouraging Britons to take part in Europe's first "Masturbate-a-thon."
Marie Stopes International is co-hosting the event in Clerkenwell, central London, with Terrence Higgins trust, an HIV/AIDS charity.
A Marie Stopes spokeswoman tells Reuters, "It is a bit of a publicity stunt but we hope it will raise awareness... We want to get people talking about safer sex, masturbation and to lift taboos."
