A Tokyo man cooked and served his own privates to five diners at a bizarre banquet in Japan.Mao Sugiyama, 22, who recently underwent elective genital-removal surgery, advertised the meal on Twitter.He originally tweeted: "Please RT. I am offering my male genitals as a meal for 100,000 yen."Will prepare and cook as the buyer requests, at his chosen location."Sugiyama, who describes himself as 'asexual', prepared the meal with button mushrooms and parsley and served it to five people.Six people had signed up for the feast but only five of them turned up to eat, although dozens more turned up on the night.The extra diners were offered crocodile-based dishes while Sugiyama cooked up the exclusive meal, reports Calorie Lab.
