In Enugu State, traditional Igbo norms that treat explicit sexual discussion as taboo coexist with rapid mobile broadband proliferation, creating conditions in which consumption frequently occurs in secrecy within marriages. This study examined pornography use frequency among married millennial couples in Enugu State, its associations with sexual communication fluency and marital conflict, and whether sexual communication mediates the pathway from pornography exposure to conflict.\n\n\nMethods\nA concurrent mixed methods design was employed with a target of 320 married millennial couples; complete data were obtained from 298 couples (596 individuals). Quantitative data were analyzed using Pearson correlations, hierarchical multiple regression, PROCESS macro mediation analysis, and Actor–Partner Interdependence Model (APIM) analyses. Twenty couples completed in‐depth qualitative interviews analyzed through Braun and Clarke's thematic analysis framework.\n\n\nResults\nPornography use was positively associated with marital conflict (r = 0.52, p < 0.001) and negatively associated with sexual communication quality (r = −0.47, p < 0.001), predicting 19% and 16% additional variance, respectively, beyond demographic controls. Sexual communication partially mediated the conflict association (ab = 0.18, 95% BC CI [0.12, 0.25]). Five qualitative themes emerged: substitution of marital sexual engagement, generation of unrealistic expectations, cultural and religious inhibition of disclosure, erosion of trust through concealment, and male peer normalization.\n\n\nConclusions\nFindings are interpreted through the Communication and Conflict Bridge framework, integrating Social Learning Theory and Relational Dialectics Theory, with direct implications for counseling practice and policy in Igbo‐speaking south‐eastern Nigeria.\n\n"]
