Polyamorists do not limit themselves to one relationship but maintain numerous relationships, straight or gay. A key element is that they are all serious emotional commitments, not just casual sex.
I have no problem with anything people might want to do in their private lives. I believe the government should stay out of people's bedrooms and private lives. However my problem with polyamorous couples, or triples, or quads, is all the new words they are introducing to the language.
Personally, I'm already having trouble remembering the words I do know, plus trying to learn Chinese and Taiwanese words; my high school French for example is rapidly disappearing. Now these people want to restructure their lives in a whole new way. Kudos to them but why do they need to do it in such a way that it requires a glossary.
If by chance one of your friends or loved ones comes out of the closet and tells you they are a poly, here's a helpful index of words you may need to know:
Poly A person with multiple serious relationship partners at the same time. They can be straight, gay or bisexual.
Vee A polyamorous relationship where one person,'the hinge', maintains a relationship with two others who are not involved with each other. The language of multiple love
Triangle A relationship between three people where each is involved with the others.
Compersion The feeling of getting pleasure from a partner's other relationships. Polys argue that this is the opposite of jealousy.
Primary Where a poly has one central relationship, perhaps with a spouse, while maintaining links to other people who are 'secondary' relationships.
If this trend takes, then we're in for some confusing moments and some really interesting family Christmas cards in the next few years.
