Introduction - The role of commercial sex in facilitating infection transmission is a subject of ongoing empirical enquiry, with little attention to the variety and extent of ‘non-traditional’ commercial services that pose a lesser risk of infection. This study sought to examine the supply and demand of a wide range of traditional and non-traditional commercial sexual services among sex workers and their clients from Queensland, Australia. Methods - Cross-sectional convenience sampling was used to compare female sex workers in 1991 (n=200, aged 16-46 years) and 2003 (n=247, aged 18-57 years) and from male clients in 2003. The client sample comprised 160 male clients aged between 19 and 72 years. Results - Over the comparison period there was a significant increase in the provision of ‘exotic’ or non-traditional sexual services. In 2003, the availability of bondage and discipline, submission, fantasy, use of sex toys, golden showers, fisting and lesbian double acts had increased dramatically, while ‘traditional’ services had mostly remained at similar levels. Moreover, the proportion of sex workers in some industry sectors providing ‘exotic’ commercial services seem to have risen over time. Conclusion - Undoubtedly, the sex industry has professionalised and now includes more sophisticated and specialized suppliers. As with any commercial business, the diversification of services is largely driven with client demand, with the ‘menu’ being generally broader than the majority of client preferences. However, although clients demands for particular commercial sexual services seems to have been met, with regard to anal sex and anal play, supply has failed to meet client demand.
