This article is situated within the framework of a doctoral research project on female domination in heterosexual BDSM (Lugand, 2017), extended by the publication of a monograph in 2023 (Lugand, 2023). It examines the ethical and methodological challenges associated with field immersion, particularly in domination salons in Berlin and Brandenburg, where the researcher confronted the stigmas linked to sex work and the marginal recognition of such subjects within academia. Drawing on social psychology, psychoanalysis, and gender studies, the article analyzes how moral panic and intense affective states influence knowledge production and the researcher-participant relationship. It also addresses the limitations of classical consent models, the management of emotional risks, and the impact of these issues on the structuring and supervision of the dissertation. The study invites a rethinking of immersive research on marginalized sexualities, emphasizing the need to reconcile scientific rigor, affective experience, and ethical responsibility.
