Beyond Pain: A Study on the Variance of Pain Thresholds Within BDSM Interactions in Dominants and Submissives.

BACKGROUND: BDSM is an acronym describing bondage and discipline, dominance and submission, and sadism and masochism. Afflicting or receiving pain is usually an important part of the BDSM interaction. AIM: This research will focus on better understanding the aspect of pain within a BDSM interaction. METHODS: Submissive and dominant counterparts of 35 couples were recruited to participate in a BDSM interaction, of which 34 dominants and 33 submissives were included in the analyses. A non-BDSM interested control group (n = 27) was included to control for social interaction, of which 24 were included in the analyses. OUTCOMES: This research investigates the differences in (i) baseline pain thresholds, (ii) the impact of a BDSM interaction on those thresholds, and (iii) threshold moderating factors like pain cognition between submissive and dominant BDSM participants and control individuals. RESULTS: BDSM practitioners have a higher pain threshold overall and a BSDM interaction will result in a temporary elevation of pain thresholds for submissives. Additionally, pain thresholds in dominants will be dependent upon their fear of pain and tendency to catastrophize pain and submissives will experience less fear of pain than the control group. CLINICAL IMPLICATIONS: By further enhancing our understanding of the mechanisms behind a BDSM interaction in this way, we aspire to relieve the stigma these practitioners still endure. STRENGTHS & LIMITATIONS: This is one of the first studies of its kind with a large sample size compared to similar research, which makes it a significant contribution to the field. It must be mentioned that there is a possible selection bias because recruitment was only done through the Flemish BDSM community and specifically those who visit clubs. Additionally, pain threshold remains a subjective measurement, which must be taken into account. CONCLUSION: This study helps shed further light on the biological processes behind a BDSM interaction through pain threshold measurements. Wuyts E, De Neef N, Coppens V, et al.

Between Pleasure and Pain: A Pilot Study on the Biological Mechanisms Associated With BDSM Interactions in Dominants and Submissives.

BACKGROUND: BDSM is an abbreviation used to reference the concepts of bondage and discipline, dominance and submission, sadism, and masochism, enacted by power exchanges between consensual partners. AIM: To shed light upon the rewarding biological mechanisms associated with BDSM interactions. METHODS: A group of 35 BDSM couples (dominant and submissive counterparts) were recruited and tested during a BDSM interaction, with an additional control group of 27 non-BDSM interested people tested in a normal social interaction. OUTCOMES: We compared the evolution of the stress and reward hormone levels of cortisol, beta-endorphins, and endocannabinoids (2AG and anandamide) in a group of BDSM practitioners before and after an active BDSM interaction with the levels in control individuals. RESULTS: We showed that submissives showed increases in cortisol and endocannabinoid levels due to the BDSM interaction, with dominants only showing increased endocannabinoid levels when the BDSM interaction was associated with power play. CLINICAL IMPLICATIONS: This study effectively provides a link between behavior that many think of as aberrant on one hand, and biological pleasure experience on the other, in the hope that it may relieve some of the stigma these practitioners still endure. STRENGTHS & LIMITATIONS: It is one of the first and largest studies of its kind, but is still limited in sample size and only represents a specific population of Flemish BDSM practitioners. CONCLUSION: Even though this is one of the first studies of its kind, we can conclude that there is a clear indication for increased pleasure in submissives when looking at biological effects of a BDSM interaction, which was related to the increases in experienced stress.
