Abstract
The exchange of money and sex has been constructed as conflictive and resulting in stigmati-zation of people who perform sex work. Sex market is signed by the tension located in the in-tersection of sexual practices and commercial/working public sphere, as well as crossed by class and gender relations. Drawing from in depth interviews with female and transgender sex workers, this article seeks to understand how the singularities of sex market propitiates the use of tactics and the materialization of symbolic embodied boundaries beyond a merely economical logic. In particular, the article focuses in the role of certain sexual practices avoided in encounters with clients, and the economical, cultural and working conditions un-der which those boundaries are consolidated or destabilized, as well as some of its “micropo-litical” consequences.
