Men polygamous by nature?

My polygamous women friends don't exist? I'll have to tell them! ;) I'm just kidding. There are people who are polygamous (or polyamorous, a more commonly used term for it) and have healthy, functioning, multiple-person relationships. Some people just don't feel like they can be with just one person. As long as everyone in the relationship is happy and secure and feels the same way, good for them! It's nobody's business but their own how the conduct their personal affairs.
