I find it interesting that two male birds find it advantageous to form a monogamous relationship.
Think about it. We would have less welfare cases at public expense if gay people formed stable monogamous relationships. If one got sick and lost his job, perhaps the insurance of the other would cover him; and the healthy one could pay the bills like the mortgage. It would be better than having people by themselves and then going on the dole.
I'm thinking about society. I also find the past statistics from National Center for Health Statistics of interest. Fewer heterosexuals are forming permanent monogamous bonds. Over 40% of the children born in 2007 in this country were born out of wedlock. This cannot be good for society. it cannot be good for our economy and the current financial troubles of the government. The latest study now has it at 41%.

Put aside the morality issues. Think economics and taxes. The lack of lasting monogamous relationships is not good for the country. It increases government spending too.
Do you know how much we spend on prisons? It's a fantastic amount; and most of the people in prison (I think it's over 80%) come from one parent households. Never mind the morality of encouraging stable marriages -- think of the financial costs to society and how these children often grow up. I think we should encourage anyone who actually forms stable relationships to do so.
Think about this. Our government actually subsidizes bad behavior. Some young girls see getting pregnant, although unmarried, as a way of getting out of their parents house. They can get money from the government to do it, too.
