British broadcaster Channel 4 is to bring mass public masturbation to the small screen. They have commissioned a documentary about the UK's first "masturbate-a-thon" as part of a series of programmes dubbed "Wank week". Hundreds of people are expected to gather in a hall in central London on August 5 to pleasure themselves in aid of charity. The organiser of the event, the San Francisco-based Centre for Sex and Culture, has run mass masturbation events in the US for the past five years to raise money for safe sex groups and plans to replicate the formula in the UK. Cameras will follow the organisers and participants for a 60-minute film, which has the working title of Wank-a-thon. It is expected to air towards the end of the year. Prizes will be on offer for those who clock up the most orgasms and those who can masturbate the longest - the current record, according to the organisers, is a chafing eight-and-a-half hours. To qualify for the record, the organisers say "at least 55 minutes of every hour shall be spent self-pleasuring by manual or sex toy stimulation" with participants getting just five minutes to "replenish and renew".
