With João Florêncio. This article draws from porn studies and queer historiographies to draw some methodological considerations about the value, benefits, and challenges posed by porn archives to the writing of queer subcultural histories. Rather than trying to solve porn’s double ontological status as both documentary and fantasy, the authors locate in that defining feature of the genre porn’s value as a historical source. Simultaneously a document of sex cultures and of the edges of morality, and a historically and culturally situated speculation on what bodies and sex may become, porn offers both cultural critics and historians a rich archive for deepening their knowledge of the intersections of culture, morality, pleasure, community, embodiment, and the politics of belonging.
