Do you have any data to back up that assertion? As a gay man with dozens of gay male friends, and hundreds of online acquaintances, I've observed that very few gay men, including married gay men, value sexual monogamy the way straight people tend to. It's not part of our culture, and legal marriage that's not to my eyes really changed much about our culture.

We value legal marriage, because we need it. For example, I lost an apartment in New York City because I was not able to legally inherit it from my partner, who at that time was not legally able to become my husband.

Stories like that are some of the reasons why we demanded the protections of marriage. Strict sexual monogamy figured very little into our thinking back in the late 90s when we began to Target legal marriage as a right we deserve as human beings.

And while you can certainly find gay people who values sexual exclusivity, it's very difficult to find any gay person who won't tell you that legal marriage is a victory just because of what it is. A civil right we need and deserve.
