The only guiding principle in this paradigm is consent. You, a free agent, can do anything you want, as long as it does not compromise the free agency of another. Let me be clear: consent is crucial. An emphasis on the importance of consent is perhaps the one good feature of this paradigm. The problem is not that consent is a primary value in this view; the problem is that it's the only value. Consent should be the starting point rather than the end of the discussion about sexual morality. It is not enough to say that the best we can expect from sex, morally speaking, is that it's not rape.
