 Another criterion is intention, though we need to figure out what the intention is for. One reasonable candidate is “the intention to produce sexual pleasure in oneself or in another”. But this is not necessary: two people who have sexual intercourse to procreate engage in a sexual act. The experience, if any, of sexual pleasure is a by-product of the action (Soble 1996: 132). This criterion is also not sufficient. Suppose that X intends to produce sexual pleasure in Y by “whistling ‘Dixie’,” but what X does is not a sexual act (Soble 2006a: 22).
