The message seems to be that a nice ass, wordlessly urging you to follow, is the best way to sell nonsexual social nudism. The models in these photos—and let’s just admit that these are models doing a job and not your average nudist—are projecting a lifestyle of health and vigor and youthful sexuality. The smiling men and women playing naked shuffleboard in the brochure for Bare Necessities’ nude cruises, the topless women chatting in a garden, the physically robust couples artfully arranged around a pool—these images lead you to believe that going to a nudist resort would be an awesome thing to do: fun, exciting, maybe even sexy. But in my admittedly limited experience—I can’t go to every nudist resort in the world—the people sunning themselves at your average nudist club are not young and energetic models; follow the beautiful buttocks in the brochure and she will lead you to a bunch of sun-ravaged retirees sitting around a pool. Which isn’t a terrible thing, don’t get me wrong.
