A Qualitative Exploration of Sleep-Related Sexual Interests: Somnophilia and Dormaphilia

Somnophilia is an under-researched paraphilia. Consequently, there are discrepancies in its definition and conceptual understanding. Also, literature regarding the sexual interest in being asleep during sexual activity (dormaphilia) is even more limited. As such, there is a need to understand these paraphilias more deeply. This study recruited 232 participants online to discuss the content, origin, sexual appeal, emotional appraisal, and behavioural enactment of their somnophilic and dormaphilic interests and fantasies. A Thematic Analysis led to the identification of four main themes: (1) Relevance of Sleep State; (2) Roles within Sleep Sex; (3) Enactment of Sleep Paraphilia and (4) Lack of Consent and Awareness. These four themes spanned across both those reporting somnophilic and dormaphilic fantasies. The Discussion explores the multi-faceted nature of the interests, and implications for the understanding of somnophilia and dormaphilia. This study provides the first qualitative exploration of sleep-related paraphilias, opening avenues for future research and practice.
