Well, having been intimately involved in Polyamory for most of my adult life and having a very successful and happy polyamorous marriage for several years now, I have to agree that it’s alot of work… but that it can work out great for everyone and be a very happy and healthy relationship dynamic.
I TOTALLY disagree about first and second (or primary and secondary) spouses. Anywhere you start designating static roles in relationships you are in for a world of trouble. It may provide seeming stability to begin with, but it usually falls apart. It does of course totally depend on the individuals, I can only tell you what’s worked for me.
I like the term polyfidelity, which is a committed and exclusive relationship between more than two partners. It seems to work best to me in a polyamorous relationship for everyone to have equal standing, there’s already going to be automatic insecurity and for everyone to be equally involved can eliminate some of the competition that tends to happen.
In my experience, having an open relationship can be very workable but way more stressful to me than a polyamorous marriage, but that’s just my experience.
I don’t find that the polyamorous aspect is any more work now that I live in the boonies in a small tribe like environment, if anything it’s easier because it’s easier to focus on us and our family without civ distractions.
Our child seems to benefit greatly as well, by having multiple role models and supporters.
I’ve seen the courtesan thing too, and to me it seems like such a civ construct and lends itself greatly hierarchy and other unpleasantness. Not to mention, that having a relationship (or even sex) to appease one’s ego (or rather, insecurity) seems less than healthy to me.
Honesty, openness and a willingness to let go of your preconceptions seems like some of the most useful tools to me.
