Published 1974, a national study of sexuality conducted by Hunt found that relatively few people engage in swinging. Hunt attributed the low number of people in these open marriages to various social, psychological, and practical problems. Yet, some of these people "confirmed what the advocates and enthusiasts have claimed—namely, that marital swinging can provide physically intense experiences, that it can be immensely ego-gratifying and that it is a temporary release from confinement and responsibility and a brief chance to live out one's wildest fantasies" (pages 273–274).
