I had a few thoughts I had on the topic. There are probably a lot of reasons. Here’s what I came up with:
- Not the marrying type of man. A (wealthy) guy with a lot of prospects who juggles several girlfriends and doesn’t really commit to any of them.
- Guy who lives with his girlfriend, but she’s not a slam dunk. He’s got a stable job and income; she likes that. But for him, why buy the cow? Also, perhaps deep down, she’s not the one.
- A guy who is philosophically against marriage and the conventionality of it and its restrictions on possible other relationships. Does not believe open marriage works either.
- A guy who doesn’t want kids, and if he doesn’t want kids, he doesn’t see the point in getting married either.
Now if you extend the discussion to gay male couples. There is a great excuse for not being married. Generally most states don’t allow you to get married. In any case, the federal government doesn’t provide similar benefits. In order to get company benefits, you may have to be domestic partners, but this isn’t the same thing.
But actually overall, I would think that most gay guys would actually tend to be more domestic types. I.e. the type who might be more likely to consider getting married if allowed.
