Christian Grov and Michael Smith paint a vivid picture of early cultures of men who have sex with men (MSM) and their close relationship to male sex work. The history of male sex work closely reflects changes within and changing attitudes toward male-male sexual encounters. Early male sex work occurred in clearly defined spaces, often the underground spaces of cinema, porn arcades, beats, and bathhouses. New information technologies and changing social attitudes have bought male work out into the space of private homes, five-star hotels, organized sex tours, and mainstream cultural venues. These technologies also have allowed greater diversity in terms of services offered and sought. Some researchers have spoken of the new tribalism that has evolved in MSM culture in the last decade. There is now a wide range of highly visible MSM subcultures, which have flourished because of new opportunities for communication provided by the Internet. This has increased diversity and made visible the polymorphous nature of sexual desire, and also created greater opportunity to find peer support in terms of male sex workers’ health needs and general welfare. However, the new “tribalism” also poses challenges in terms of promoting public health. Unlike the early phases of the HIV epidemic, there now are clearly many gay communities to speak to rather than one clearly defined gay community. This noted, there has in fact never been a single gay community. It has always been fluid, contingent, and improvisational, with shifting boundaries and conflicts. This merely reflects the diversity among MSM in terms of how they themselves perceive and live their lives. Post-AIDS researchers have described increased division within gay communities, as men develop diverse responses and sexual expression relative to HIV. Thus the term “tribes” has been suggested as one that accurately describes homosexual sociality. Indeed, there is wide variety among the male sex workers who service MSM and their diverse tastes, once again making male sex work a microcosm that reflects wider changes in MSM cultures and subjectivities.
