The PsySexSomatic Framework: A Conceptual Model of Pelvic Sensory Reintegration, Interoception, and Reward-Associated Processes in Sexual Trauma Recovery

This conceptual white paper introduces the PsySexSomatic (PSS) framework, an interdisciplinary theoretical model exploring pelvic sensory attenuation, interoceptive disruption, and reduced pleasure responsiveness following sexual trauma. The framework proposes a novel conceptual integration of pelvic sensory processes, affective neurophysiology, and reward-associated neuroplasticity as potential contributors to embodied recovery processes. It introduces the P-DAST construct (Pleasure-Deficit and Sensory Attenuation in Trauma) as a descriptive pattern of post-traumatic psychosexual adaptation. Drawing on interoceptive theory, affective touch research, and reward-based neural mechanisms, the model outlines a non-clinical, exploratory mapping approach to pelvic sensory organization and regulatory processes. This work is presented as a theoretical and research-oriented contribution and does not constitute a clinical protocol or therapeutic intervention. It is intended to support future interdisciplinary research at the intersection of psychosexual health, trauma, interoception, and embodied regulation.
