In addition, the increasing use of the internet and mobile phones has changed patterns of sex work in Peru. In many cases, the practice appears linked to ideals of social mobility, migratory experiences and other economic activities. We found that CSMT in Peru takes many forms (some not previously described in the country) and is practised in different places by people from various socioeconomic levels. The study included participant observation in sex work venues and interviews with 42 sex workers and 25 key informants. This paper presents findings from an ethnographic study of the characteristics, patterns and socio-cultural aspects of CSMT in three Peruvian cities. However, in reality little is known about the complexities of this practice in Peru. In Peru, commercial sex involving men and male-born travestis, transgenders and transsexuals (CSMT) is usually represented as a dangerous practice carried out on the streets by people experiencing economic hardship and social exclusion.
