Ronald Weitzer shows that although some of the central pillars of Thailand’s sex industry remain unaltered over the past four decades, in other respects there has been a profound transformation. In the sector oriented toward foreign visitors, the number of sex businesses and independent operators has grown numerically and geographically; customers are increasingly diverse in race and nationality; paid sexual encounters are no longer confined to young Thai women and older white men; transgender women comprise a significant share of the workforce; and technological advances give participants more autonomy than ever before. Sex Tourism in Thailand explores these developments in conjunction with related structural and experiential dimensions in an illuminating account of sexual commerce in Southeast Asia.
