On Wednesday, I joined a hundred other voyeurs at the Rock 'n' Roll Hotel in D.C. to watch air guitar's scandalous sister sport, air sex. Air sex, as the name implies, is a theatrical sexual performance with an imaginary partner. The Air Sex competitions are to be held in 16 cities across the U.S., culminating in the World Air Sex Championship where the Ultimate Air Lover will be crowned. (It would have been 17, but the Utah venue, facing a threat of a revoked liquor license if it hosted the event, backed out.)
