This is science, people! Well, okay, science from 1998 rehashed for a Daily Beast listicle, but still! Jews and agnostics (and look, who do you think invented doubt?) have 20 percent more sex than the average. (Baptists are also above average, albeit less so; Lutherans and Presbyterians, the poor schmucks, apparently have less sex.) Also, according to another study (this one published last year), observant married Jewish women are more than twice as likely as average married women to have sex three to six times per week, which, depending on whether you’re Annie or Alvy, is “constantly” or “hardly ever.”
