An underground narrative has long been whispered among transgender men: after coming out as trans, many of us develop an attraction for other men. In this hybrid documentary, history comes alive when an Iranian-American transman time-travels on a dizzying quest to unravel his own sexual desires. As Ahmad approaches age 60, his long-suppressed desires for other men become impossible to ignore. Having grown up in an era when homosexual activity could block one’s access to medical transition, he can’t help but wonder whether his sexuality and gender identity are completely at odds. He turns to the LGBT archives for answers, where he meets a 20-something trans archivist named Kieran. As Ahmad falls deeper into the archive, he is quite literally sucked into the text—becoming a time-traveler who participates in the queer cruising history he reads about. This fictional narrative is interwoven with archival gems and a trove of contemporary oral histories from a diverse group of transmen across North America. These participants candidly discuss the evolution of their desires and illuminate their struggles with gender (non)conformity, fetishization, transphobia, sexual racism, and safer sex. Desire Lines pushes against binaries—fiction vs. non-fiction, reality vs. fantasy, public vs. private—in order to highlight the fallacy of “purity” that undergirds colonialist notions of discrete categories of being (or genre); embracing bewilderment as a liberatory strategy for trans representation.
