Gym showers, sex parties, European beach holidays, walking into the wrong changing room, a knife fight in a bathhouse: there are so many ways to be naked in front of strangers. Some of them are even legal.
Shivering naked with 2,000 people on a Tasmanian beach on a winter morning is legal, if not usually my idea of a great day out. But when given a waiver form asking you to sign away the risk of a heart attack and showing your arse on national television, who refuses that kind of invitation? Not I.
