Sex columnist and It Gets Better creator Dan Savage stopped by The Colbert Report last night to discuss the merits of monogamy in marriage. Earlier this month in a New York Times Magazine profile, Dan argued that straight couples put too much weight on monogamy, which is problematic because many aren't very good at it. Stephen countered that if you don't have monogamy, a marriage is nothing more than a joint checking account. Dan went on to clarify his argument, explaining that if a couple agrees to monogamy, each spouse should honor that promise, but that we should be more realistic about what it takes for some to be sexually satisfied. Watch the two hash out the importance of only having sex with your spouse below.
