How should we understand the bugarr�n, a man who has sex with other men while regarding himself as heterosexual? Reaching beyond queer and gay studies, Ram�n E. Soto-Crespo's research suggests that this paradoxical figure mutated into what he calls the "neobugarr�n," a neoliberal market-oriented actor who used the traditional sexual practice as an optimizing strategy for manipulating the forces of globalization during the 1990s. In Neobugarr�n: Heteroflexibility, Neoliberalism, and Latin/o American Sexual Practice, Soto-Crespo chronicles the cultural modifications of bugarr�n, a distinct male-male sexual practice in Latin/o America and the Caribbean, during the twentieth and twenty-first centuries. Working with and against Foucault and Kinsey to examine diverse works from anthropology, literature, cinema, and social media, he investigates a wide array of bugarr�n sources, ranging from previously underexamined multimedia to ethnographies, fiction, films, and beyond. These works constitute a neobugarr�n archive and attest to a sexual practice currently metamorphosing on the cusp of extinction. Soto-Crespo's analysis challenges conventional understandings of "heteroflexible" sex between men and reveals a hitherto unnoticed transformation in neoliberal ecologies of bugarr�n sexual practice.
