Andil Gosine asks whether sex and sexuality have been left unconsidered in international development or not. Sex and sexuality he argues have always been at the heart of development. Three figures have haunted the project of international development: Monster, Womb, MSM (‘Men who have sex with Men’). Anxieties about the sexual proclivities of these figures have driven and shaped the project of international development, both as a teleological metanarrative and in its material application. He proposes that neither silenced nor neglected, sex works in service of development, providing both the rationale and means through which to authorize and institute heteronationalism.
