Okami - Hah! Love it. To your first question - no, not unless the polyamorous individual decided to join a polygamous sect and adopt their ways. To the second question - no idea! Never heard that one before. But many do have various religious beliefs. It's just not the basis behind their sexual behavior. You need to look at the descriptions behind each as a whole since I'm more describing a culture than a strict definition. Unfortunately, I'm not good enough with words for that.

I get the point you're making about definitions though, and I agree. We tend to make up more and more new terms regarding sexuality, and in some cases (like with omnisexuality and pansexuality) I agree that it's pretty redundant. In this case, I can see where the separation is made though. A lot of this comes from the fact that Western culture has traditionally been very closed to what we now consider to be alternative sexual practices and desires (everything from fetishism to homosexuality to pansexuality could be included here). There's bound to be a period where lots of new terms are created as people who have never had a voice start to unite and define themselves.

Pandoren - It can be a triangle relationship. However, this isn't necessarily the case (and I've also seen a lot of problems arise with this type of relationship). I always worked my relationships as being individual. If I like someone and one of my current partners doesn't, I can pursue that and they can choose not to. If they like someone who I don't really wish to become involved with, they are free to pursue that person and I don't get a major say in it. For one person, it looks a lot like the center of a wheel with a lot of spokes pointing out. Except as the end of each of those spokes is another person with the center of their wheel. In my last relationship there were about 8 people total and it would have looked more like a kaleidoscope if we'd drawn it out. The main issue in these situations is jealousy and time. One relationship can be very difficult to manage. Imagine having five - especially when you're working a lot. It's pretty easy for feelings to get hurt, particularly if some people are very sensitive.
