The main aim of this chapter is to show that sexuality and capitalism are intrinsically related. Such an endeavour demands extracting sex from the domains of nature, reproduction, and the private, and relating it to the intricate norms of capitalism. The first part of the chapter looks at why capitalism and sexuality have been articulated as belonging to separate spheres of life. How did it come to seem that “being a sex” and “having sex” is so entirely removed from the “investment of money to make more money”? The second part of the chapter provides an overview of the historical evolution of capitalism and its relationship to sexuality, focusing on the nineteenth-century transition from the household family-based economy to a fully developed capitalist free labour economy. The main characters of this chapter are homo economicus and his economically invisible wife, the producers of valuable social relations, as well as various “reformable” or “irreformable” others whose sex is deemed of no value or even against value. The chapter presents social relations as capitalist and sexual, and treats the dichotomies social–natural, public–private, and economic–cultural as interwoven in the (de)politicization of both sexuality and capitalism.
