<p><?tk 2?>This article explores the cultural significance of penis size as a motif in eighteenth century Spanish erotica. While Masculinity and Sexuality Studies have addressed phallic representation across a range of empirical and psychological frameworks, this study focuses on the poetic strategies through which penis size is indirectly depicted—eschewing conventional measurements in favor of symbolic or allusive forms. I argue that this rhetorical obliqueness reflects broader Enlightenment anxieties surrounding race, gender, and power. Through close textual analysis and historical contextualization, I demonstrate that phallic representation functions as a mechanism of racialization, othering, and the regulation of female sexuality. Drawing on Theodor Adorno’s critique of Enlightenment rationality, the article establishes a genealogy of phallic discourse that connects eighteenth-century erotica to modern ideologies of masculinity and sexual regulations. In doing so, it contributes to an expanded understanding of the intersection between sex, literature, and Enlightenment thought.</p>
