A recent ?Fidelity Survey? in Playboy magazine asked 1,432 married men and women if they had ever cheated on their partner. Seventy-five percent of men and 82 percent of women said no. Half the men and 66 percent of the women even said they've never even entertained thoughts of infidelity.Not to sound absolutely cynical, and not to put down the hard work of the sociologists behind this study, but I'm dubious about the results. Especially given that Playboy readers are groomed to fantasize about doing it with a different Pet or Playmate each month!
