This dissertation examines the mutual constitution of sexuality and debility in contemporary Sinophone literature and media. Bridging disability studies and sexuality studies in Chinese and Sinophone contexts, it argues that sexuality and debility are not discrete, parallel categories but intertwined modes of bodymind variation that unsettle dominant configurations of subjectivity and relationality. Spanning Taiwan and mainland China, the three chapters track different modalities through which sexuality and debility intersect and reshape the terms of desire, agency, and cultural legibility.Chapter One probes the legacy of Qiu Miaojin, the iconic queer Taiwanese author whose suicide in 1995 has been alternately medicalized, aestheticized, and monumentalized. Reading subsequent works by Lai Hsiang-yin, Yeh Ching, and Li Kotomi alongside Qiu’s fiction and diaries, the chapter traces a lineage of queer-mad death and survival—a lineage that resists at once the pathologization of queer madness, the romanticization of queer martyrdom, and the triumphalist narrative of LGBTQ+ progress consolidated by Taiwan’s 2019 legalization of same-sex marriage. Chapter Two analyzes the self-presentation of Hand Angels—a Taiwanese nongovernmental organization that provides volunteer sexual services to disabled individuals—alongside Hu Shu-wen’s fiction about sexual assistance. It contends that the humanitarian framework through which disabled sexuality becomes recognizable cannot purify itself of the hierarchies it claims to dismantle; Hu’s fiction dwells precisely in the contamination, ambivalence, and co-implication that humanitarian discourse tends to disavow. Chapter Three turns to the tropes of castration and eunuchism in the Chinese popular imagination, attending to the widespread use of castration as a metaphor for censorship, on the one hand, and the flourishing of a romance genre known as “eunuch fiction,” on the other. Proposing the concept of an “erotics of castration,” the chapter explores how the “castrated” text under censorial pressure and the castrated body of the eunuch-hero come to mirror one another: both undergo acts of cutting that paradoxically intensify their appeal and open up erotic and creative possibilities. Across these cases, the dissertation demonstrates that regulatory regimes—psychiatric, humanitarian, and censorial—do not simply constrain nonnormative bodyminds and sexualities; they also generate the unruly desires, textual afterlives, and cultural excesses they seek to contain. “Troublesome bodyminds,” then, are not merely bodies and minds marked as problems; they are figures through which the norms governing desire, capacity, and relational life become troubled in turn.
