In the New York Press:

Varied approaches to sexuality is probably the most taboo of the constructs that same-sex couples may import into marriage, and one that Coontz, of the Council on Contemporary Families, approaches very delicately. "I want to be very careful about how this is phrased, but there is a prevalence among some same-sex relationships, particularly gay male relationships, to establish long-term commitments while allowing for nonmonogamy," she says. "While this is not for every opposite-sex couple, just as it is not right for every same-sex couple, it is one of the ways that some people may handle the pressures of a world where people want partnerships but live long lives and have frequent opportunities."
