All sex is not created equal, and some places are blessed with more of it than others. We travel to Hurley, Wisconsin, a town with the unlikely distinction of being the Strip Club Capital of America. Know where to find the fastest-growing group of sexually active people? We head to Delray Beach, Florida, where senior citizens are turning retirement communities into sexual meccas. And as more countries experiment with legalized prostitution, we journey to Switzerland, to a drive-in brothel in Zurich.
