Research on the dynamics of corruption has rarely considered sex as a currency in corrupt transactions. This article puts forward the argument that the abuse of entrusted power in exchange for personal gain is relevant also when sex, rather than money, is the currency. It then contributes with a careful conceptualization of such transactions as sexual corruption. Anchoring our conceptualization in the abuse of entrusted power, the article defines sexual corruption, its elements, categories and delimitations, and proposes a conceptual framework that can be used to develop research on sexual corruption. We also address the implications of recognizing sex as a currency in corrupt transactions, providing insights as to why abuse of power is often overlooked when sex is the currency of the transaction. Our approach offers analytic precision and contributes to setting an agenda for the study of sexual corruption as an obstacle to good governance, at a time when efforts to collect data on sexual corruption are increasing.
