If there's one thing I've learned since my entrance into the lifestyle, it's that there's more than one form of poly. A polyamorous relationship can be any one of an infinite number of arrangements. So it makes sense that the ideal arrangement for different people would be different as well.
Before I'd considered the ideas of polyamory, bisexuality, or dating in general, I'd wondered what it would be like to date a man and a woman at the same time. The two would also be dating each other, or we would disregard the "couples" idea and just be together as one triad. This sort of dynamic came back to me once I'd discovered polyamory was an option, and I began dating a married couple. For that brief time it felt awesome, not unlike what I'd imagined it to be.
That arrangement is now partly over (still dating the husband, FwB with the wife), and I miss being with a woman. Perhaps it's the hedonist in me that wants a little of everything. I'd like to be part of a triad again in the future, open or otherwise, even if I don't see that happening in my current situation.
What was your vision of an ideal relationship, poly-wise? Has that changed at all? Or do you disregard "ideals" entirely and just go with the flow?
