Abstract: Employing queer, decolonial, and asexual frameworks, this paper offers the language of homointimacy and homointimate friendship to read the platonic, yet deeply queer, relationship between Teresa and Alicia in Ana Castillo’s The Mixquiahuala Letters. While relationships with men are evident throughout the novel and often serve as subjects of the women’s correspondence, I challenge the heteronormative gaze that governs most readings of the novel by illuminating Teresa and Alicia’s homointimate bond and its disruption of the colonially constructed platonic/romantic binary. Revealing how the queer decolonial narrative structure of the novel aids in interpreting Teresa and Alicia’s queer relationship, this article invokes a decolonial imaginary attuned to queer asexual life to assert new ways of seeing and knowing “queer” beyond sex and sexual attraction. While most scholarship on queer Chicanx identity and relationships centralizes the subversive nature of queer sexualities against the demands of compulsory heterosexuality, this article seeks to elevate the equally liberatory and transgressive nature of homointimate friendship which equips us to better understand “queer” as an expansive, radical mode of relating often inclusive of, but not inherently dependent on, sex and sexual attraction.
