 “Good sex” most obviously refers to pleasurable sex. A sex act can be good or bad depending on the amount and intensity of the pleasure or pain it provides (Vannoy 1980: ch. 3), though pain in sex can contribute to its pleasure (in BDSM sex, e.g.). We must keep in mind the different senses of “pleasure” that can come into play, though pleasure-as-sensation and pleasure-as-enjoyment are crucial because they are often the reason people pursue sexual activity. Imagine the sexual experience of a woman forced into marrying someone she finds undesirable, even revolting. Such negative emotions provide the crucial reason why consent is necessary. Note also how negative evaluations border on the moral: a disgusting sexual experience is both painful and, perhaps because of this, leaves a bad moral taste in one’s mouth.
