Some philosophical accounts imply that masturbation is inferior sexual activity. Against this, Soble argues that masturbation is central. Relying on the physical-anatomical indistinguishability of sexual act-types, he derives a Zeno-style paradox about sexual activity: either all sexual activity (even ordinary coitus) is masturbatory or none of it is (not even solitary masturbation). Soble argues for the first horn of the dilemma, thus ensuring that solitary masturbation is a member of the continuum of sexual activities. Going beyond anatomy, Soble also argues that the central psychological features of paired sexual activity are normally exhibited also by solitary masturbation, which further establishes that solitary masturbation is on the continuum of sexual activity. Altogether, Soble's arguments support a "unary" model of sexuality, compelling us to take seriously the genuine sexual nature of solitary masturbation, a result that is important for the philosophy of sex, the scientific study of sexuality, and the politics of human sexuality.

In this essay, Soble addresses the various attempts in the philosophical literature to solve the "Kantian sex problem"—people's mere instrumental use of each other (and allowing themselves to be used as such by others) during sexual activity and the diminishing of one's sexual rationality and autonomy when experiencing sexual desire. The problem won't be solved by denying Kant's account of sexuality or the validity of his Formula of Humanity, but by fashioning a sexual ethics consistent with Kant's views. Soble critically discusses and rejects various proposed solutions to this problem, from behavioral and psychological internalist solutions to minimalist and extended externalist solutions. Soble also scrutinizes the writings of Kant to make sense of the passages in which Kant himself tries to solve the problem that he created. Soble concludes that Kant's restriction of sex to marriage derives as much, if not more, from the duty to protect one's own personhood from the noxious objectifying nature of sexual desire, as from the duty to protect the personhood of those whom one sexual desires and interacts with.

Relying on a sexual encounter that he had once while in graduate school, Soble explores in this essay two important and under-explored ideas in sexual ethics. The first is whether there are sexual duties to others (including, even especially, to strangers), and what the source of such duties might be. He provides good reasons, rooted in both religious and secular thought, for believing that such duties exist. The second is whether there are supererogatory sexual actions—sexual actions that go beyond the demands of duty—and what conditions an act needs to satisfy in order to be supererogatory. Soble uses the sexual encounter that opens the essay to test our intuitions about these two ideas and his own arguments, and to underscore the complications involved in attempting to find secure answers as to whether some sexual acts are dutiful, done from duty, or supererogatory.
