An article in the January 28, 2010 issue of the New York Times cites a study that indicates that, contrary to the defenses offered for a change in law, gay marriage does not nudge homosexuals toward monogamy:

“A study to be released next month is offering a rare glimpse inside gay relationships and reveals that monogamy is not a central feature for many. Some gay men and lesbians argue that, as a result, they have stronger, longer-lasting and more honest relationships. And while that may sound counterintuitive, some experts say boundary-challenging gay relationships represent an evolution in marriage — one that might point the way for the survival of the institution.

“New research at San Francisco State University reveals just how common open relationships are among gay men and lesbians in the Bay Area. The Gay Couples Study has followed 556 male couples for three years — about 50 percent of those surveyed have sex outside their relationships, with the knowledge and approval of their partners.”
