Hong Kong has a bewildering range of sex businesses offering services to suit all imaginable tastes: from the glitzy nightclubs of Tsim Sha Tsui East, through the saunas, karaoke lounges and one-woman brothels of Mong Kok, to the streets and short-time hotels of Sham Shui Po. Chinese-language sex magazines print reviews of individual prostitutes, and promote an ever-widening array of bizarre sexual practices. Even mainstream newspapers engage pimps as columnists. Business appears to be booming - but there are hungry newcomers to this underground economy. How do local prostitutes deal with the ruthless competition posed by an endless supply of girls from mainland China? To find out, Yeeshan Yang spent a year gaining the trust of the city's sex workers, interviewing 50 hookers, hostesses, toy boys, transsexual prostitutes, mama-sans and brothel owners. The result is an eye-opening book which shows the human side of sex for sale. Whispers and Moans contains tales of easy money, financial ruin and hopeless relationships - and rare first-hand insights into Hong Kong's huge but hidden sex industry.
