In this theoretical paper the authors explore the connections between BDSM (i.e., practices involving bondage, discipline, dominance, submission, sadism, masochism) and CSA (childhood sexual abuse) in order to investigate the potential unconscious mechanisms at play and the therapeutic functions of BDSM practices among CSA victims. Drawing on the embodiment framework, the authors address how BDSM may serve as a form of unconscious repetition of traumatic experiences for certain CSA victims, with the aim of processing trauma and healing. A review of the empirical evidence regarding the links between BDSM and CSA trauma, along with the potential of BDSM to trigger trauma and elicit dissociation, guilt, or shame, is conducted. Finally, BDSM practices are reviewed through the concept of trauma-play, which involves deliberate rescripting. In short, the complex relationship between BDSM and CSA is highlighted, as well as its implications for understanding and potentially addressing trauma experiences in therapy.
