 There is general consensus among philosophers that valid or genuine consent (henceforth “consent”) by all the parties to a sex act is necessary and sufficient for the moral permissibility of the sex act (Archard 1998; Mappes 1987; Miller &amp; Wertheimer 2010; Primoratz 2001; Wertheimer 2003; but see Pateman 1988), though what valid consent consists of is an intricate issue (to which Wertheimer 2003 is dedicated). Yet the sufficiency of consent can be questioned. If, for example, sexual desire by nature objectifies, as the Kantian view has it, then the consent of the parties is insufficient—they consent to a wrong action (see below).
