 Moreover, sexual pleasure seems to be the primary motive for sexual activity: although sexual activity has other goals (Meston and Buss 2007), few people would have sex just to exercise, to boost their self-image, or for revenge, and although many people would have sex just to procreate, procreation would plummet were sex to not be enjoyable. It then seems that sexual pleasure provides a basic motive for sexual activity that underlies multiple other motives.
