Heteronormativity and heterosexual reasons are among the reasons I didn't push to get legally married--sheer laziness was the primary reason, mind you. With the rise of domestic partnership legislation and legal marriage in some countries, I don't feel as guilty about marrying a man myself. We've been together for almost twenty years, and are doing this for pragmatic as well as romantic reasons (so he can get my health insurance). Of course we decided to do this just before my company *finally* decided to extend coverage to domestic partners of either gender, so we could have simply signed a domestic partnership thingy. But if we were going to go to that trouble, we might as well have a courthouse marriage ANYWAY...so that's what we're doing.
