Objective Bondage and discipline, dominance and submission, and sadomasochism (BDSM) practitioners are at increased risk for suicidal thoughts and behaviors. We hypothesized the association between (a) lifetime frequency of BDSM‐related sexual behaviors and (b) BDSM identification and suicide attempt status would be mediated by acquired capability components (i.e., fearlessness about death and pain tolerance). Gender differences were examined. Method Participants were 576 BDSM practitioners (meanage = 28.71; 66.7% male) recruited from online BDSM‐related groups, cross‐sectionally. Results Among males, the total indirect effect of acquired capability components in the relation between BDSM‐related sexual behaviors and suicide attempt status was significant. The specific indirect effect of perceived pain tolerance in the relation between both BDSM‐related sexual behaviors and BDSM identification and suicide attempt status was significant. There were no significant effects for females. Additionally, 12% reported a suicide attempt history. Conclusion Among males, BDSM‐related sexual behaviors and BDSM identification were associated with increased acquired capability components, which were positively associated with suicide attempt status.
