Sex work is "the exchange of sexual services, performances, or products for material compensation. It includes activities of direct physical contact between buyers and sellers as well as indirect sexual stimulation" The term emphasizes the labor and economic implications of this type of work. Furthermore, some prefer the use of the term because it seemingly grants more agency to the sellers of these services.
Because of the agency associated with the term, "sex work" generally refers to voluntary sexual transactions; thus the term does not refer to human trafficking and other coerced or nonconsensual sexual transactions. Due to the legal status of some forms of sex work and the stigma associated with sex work, the population is difficult to access; thus there has been relatively little academic research done on the topic. Furthermore, the vast majority of academic literature on sex work focuses on prostitution, and to a lesser extent, exotic dancing; there is little research on other forms of sex work. These findings cannot necessarily be generalized to other forms of sex work. Nonetheless, there is a long documented history of sex work and its personal and economic nature.
Types of sex work include, but are not limited to, street prostitution, indoor prostitution (escort services, brothel work, massage parlor-related prostitution, bar or casino prostitution), phone sex operation, exotic dancing, lap dancing, webcam nude modeling, pornographic film performing, and nude peepshow performing. The list is sometimes expanded to include jobs in the sex industry that less directly involve the sexuality of the worker in the exchange of sexual performances, services, and products, such as the producers and directors of adult films, manufacturers and sellers of sex toys, managers in exotic dance clubs, escort agents, bouncers, etc.
In 2004, a Medline search and review of 681 “prostitution” articles was conducted in order to create a global typology of types of sex work using arbitrary categories. 25 types of sex work were identified in order to create a more systematic understanding of sex work as a whole. Prostitution varies by forms and social contexts including different types of direct and indirect prostitution. This study as conducted in order to work towards improving the health and safety of sex workers.
