Modern urban life is increasingly characterized by specialized erotic worlds designed for sexual partnership and sexual sociality. In this article, I build on sociological theory developed in areas other than the sociology of sexuality to formulate a framework uniquely suited to the analysis of such modern erotic worlds—the sexual fields framework. Coupling Goffman's social psychological focus on situational negotiation with a Bourdieusian model of routine practice, the sexual fields framework highlights the relationship of interactional work to fields of objective relations wherein historically specific erotic schemas acquire a structural manifestation that erotic players must navigate. In so doing, the sexual fields approach advances a set of sensitizing concepts for identifying the structures of collective sexual life, and raises a set of new lines of sociological inquiry, including the relationship of sexual fields to both psychoanalytic and macro-level structures and processes.
