So which country should American tourists hoping to get a little on the side visit? Britain, according to a new survey. Britain's people are the most promiscuous of any western industrial nation. The study is based on number of one-night stands, total numbers of partners and attitudes to casual sex. The United States came in sixth, behind Britain, Germany, the Netherlands, Czech Republic, and Austria. Tourists willing to travel a bit more off the beaten path to non-industrialized nation may find even more, er, pregnant opportunities. Finland and the Baltic states outscored Britain.
