BDSM is no longer treated as a manifestation of the darkest twists of the human soul but rather as a sexual activity like many others. Moreover, the philosophy of sex and much of popular culture has come to embrace BDSM for its models of consent, exploration, and freedom. Yet celebrating BDSM without deeper reflection can obscure some serious moral issues. In this chapter, I present an overview of the moral issues raised by BDSM, and I argue that it is reductive (...) to see BDSM as a simple or straightforward model for how to practice egalitarian sex. Yet, BDSM communities grapple with issues of consent, autonomy, and power in important ways, which can help us think through broader issues in sexual ethics. Either way, BDSM must be understood in its full complexity. (shrink)
