Based on interviews and ethnographic fieldwork within BDSM communities in Sweden, this article focuses on links between non-monogamy and BDSM. Drawing on Halberstam´s concept of queer space, the following questions are investigated: What are the connections between BDSM and non-monogamous communities? How does interaction between BDSM and non-monogamous practices create non-normative logic? The transgression of one norm makes it easier to transgress other norms as well, providing opportunities to find new ways of organizing relationships beyond the norms of monogamy. In order for an individual to be able to fully explore kinks in BDSM practices and at the same time respect the boundaries of a partner, nonmonogamy emerges as one logical answer.
