So, a question for Will Wilkinson et al (and judging by the commentary, there's a lot of al out there): If your wife/monogamous partner sought regular sexual gratification through watching prostitutes have sex with one another, you would have no grounds on which to feel jealous or perturbed? No grounds for feeling that they were being in some sense unfaithful? Really?

My point here, to be clear, is not that regularly watching hard-core pornography is exactly the same thing as committing adultery. My point is rather that there's a consistent continuum here - as opposed to the sort of inconsistent continuum that Will accuses me of mustering - that links the varying ways that a person who's committed to sexual monogamy can find sexual gratification outside of marriage. And I think that regular consumption of hard-core pornography is closer to the actual adultery end of the continuum (insofar as it involves actual-existing other people and actual physical acts) that it is to the "occasionally entertaining sexual thoughts about that cute girl on the subway" end of the continuum, and as such it's not "insane" to see morally meaningful similarities between porn-watching and cheating on your spouse.
