I done following sports nude: Running(Bare Buns 5k Run), Volleyball, Tennis, Basketball, water polo, surfing(once) soccer and ultimate Frisbee. I also done nude scuba diving if you consider that to be a sport, and biking. I also forgot strip poker. Also in college I also paid game we kind of made up called strip chess. Its weird to found out that independantly others have come up with simular.
Sports that I wouldnt mind playing nude but havent would include Greco Roman Style wresling, baseball, minuture golf(prefer it over regular golf)), and Advanced Dungens and Dragons
