I'd still postulate that experience is not 100% transferable, and it still involves skills that cannot be developed overnight. The whole prospect could just be too extreme or risky for someone to consider if they feel that they have too much to lose in the event that there's a hiccup along the way. And lets face it, there are very few paths in life that don't involve a few speed bumps along the way.
But we're not talking about water wings in the pool before you learn to swim, or training wheels on a bike, or learning simple math before tackling calculus.
We're talking about holding onto a concrete block because you're afraid of the ocean. The method of using the type of rules that Ceoli is talking about (hereafter referred to as "rules" in spite of the fact that there are other situations that other people also use the term "rules" for) is something that has to be
unlearned in order to learn the skills for the non-prescribed-rules relationships. It's much more difficult to learn to swim if you dive out for the first time holding onto a concrete brick and you only want to let go of it one finger at a time.
So if it's someone's first time with relationships, learning the skills of communication and self-analysis are not only more profitable in the long run, but run counter to the rules method. These skills do indeed take time to learn, and trying to learn them while simultaneously practicing methods that directly contradict those skills you are attempting to learn is probably the most inefficient way to learn something new.
The skills that make poly relationships most effective and healthy are the exact same skills that make monogamous relationships most effective and healthy - communication (which covers talking, listening, and non-verbal communication), care and consideration, starting with partners who are already similar in goals/mindsets/worldviews, self-analysis, honesty with self and with others - these are all things that good monogamous relationships also have.
If you don't have these in your monogamous relationship before you open it up, making prescripted rules won't teach them to you and will often prevent you from learning them at all. If you do have them in your monogamous relationships, you don't NEED the prescribed rules because these skills cover everything that the prescribed rules are supposed to cover.
It may be that we're still talking about slightly different
Stop right there. Can we go back now to the types of rules Ceoli was referring to, so we can stop arguing that these two different concepts aren't the same thing?
In the meantime, I would still submit that in certain contexts rules will still be valid and valuable tools, particularly for those who have spent their lives working on one relationship and are suddenly having to play catchup on an entirely new way of being, as opposed to those who have spent that name time refining the skills required for non-monogamous relationships.
I came from a monogamous culture, like most of us did. I didn't even have the benefit of learning about the swingers, the kinksters, or even the hippies until I had already started dating. Where I grew up, there were 2 options and only two options: life-long monogamy or slutdom.
My parents met when my mother was in high school, got engaged at her senior prom, and remain married. Most of my extended family married young and stayed married. I knew about divorce and remarriage, but the end goal was always the same. There was a pattern: you met someone, you had a few dates that were usually diner and a movie, you were "dating", you got married, then you had sex and kids. You moved to the suburbs and bought a dog. That was it. All effort was then aimed at preserving the marriage at all costs, even if it meant you just didn't talk about things that could upset people. (My mother refuses to hear of my dad's time in the air force before they started dating out of fear that she might learn he had other sexual partners, because some military men did, especially those who spent time overseas.) No variation on the theme whatsoever.
Then there were a few people who did not choose that path. But their alternate path was all the same too, with no variation. These were people who did not develop emotional relationships with anyone-- they just had lots of sex. That's it, the two options I was presented with when I developed my own relationship habits. So my early relationship skills come from the very typical form of "monogamy" that our society likes to think everyone has, including all the rules that dictate other people's behaviour and poor communication. I had a lot of playing catch-up to do to get to where I am now.
My point with this rambling story is that I read a lot about these people who called themselves "polyamorous" and I watched how everyone had screwed up before I came along. I tried not to make the same mistakes.
I jumped right into prescriptionless polyamory without trying all these other mistakes first.
Of course I made some mistakes of my own, and I had to build my communication skills and everything else, but I did not have to try the method that all the "experienced polys" opposed first.
A few relationships into this whole poly experiment, I did try the rules method, to make someone feel more secure about attempting something new and scary. We started out monogamous and "eased" into it with a bunch of rules. Predictably, the rules backfired exactly as all the experienced polys said it would.
Every relationship disaster I've had can be traced back to falling on those old bad habits, either on my part, on his part, or on both. Every relationship success I've had can credit its success directly to those skills required by prescriptionless relationships, even the ones where we had to learn a skill as we went along were better than those we used the old bad habits for.
