A man holds the record for masturbating almost ten continuous hours!

His name is Masanobu Sato from Japan, and he went 9 hours and 57 minutes continually masturbating at the annual Masturbate-A-Thon in San Francisco. Believe it or not, he does have a girlfriend. Sato lives with his girlfriend and practices several hours every day to ensure that he wins his competitions and keeps the world record. She takes the whole deal pretty well, as she considers it his hobby. 

To train, Sato swam twice a week for endurance and gained 5 kgs of muscle. He says his goal is to make masturbating less taboo around the world and treats his hobby like a real sport. The Masturbate-a-thon is put together by the Center for Sex and Culture, where the yearly competition is held in a place called 'The Masturbatorium.'
