Sex toy manufacturer, Aihuirun sponsored dubbed "Wankathon" China’s first ever "World AIDS Day Masturbation Contest" which took place on December 1, 2012.

This contest is somehow similar to San Francisco's annual Masturbate-a-thon. However, there was no full front nudity during the contest.

Ten masked men participated in the "No winner" contest and their genitals were hidden with orange buckets that would later reveal the fruits of their labour. To keep enthusiasm up for the contestants, scantily clad models danced around with sex toys and blow-up dolls.

The current world record holder of the ‘Longest Time Spent Masturbating’ is Sonny Nash. The pornstar ‘pleasured himself’ for as long as 10 hours and 10 minutes in May, 2012.
