I'm with dakid and Y-Girl on this.
This very topic has come up with me lately, in trying to describe my relationship with Violet to people.
We both allow the other to date and/or have relationships outside or inside our relationship. BUT we do NOT consider ourselves to have an open relationship.
We both encourage the other to pursue sexual exploration outside of our relationship. BUT we do NOT consider ourselves swingers.
We are a very happy, very committed couple comprised of two people who both owned the term "slut" a looong time ago, and could not care less what the rest of the world decides its implications are. We both see the value in a committed monogamous-style relationship, and we both acknowledge that in the long term, it hasn't worked out all that well for either of us in the past. I don't mind her dating women, and can wrap my head around her seeing other guys; she knows that seeing guys isn't on my list, but she actively encourages me to see other girls, and frankly, pushes me toward sexual encounters of any kind with them, casual or not.
And all of that has always ended up bringing us closer. Even the disaster with Anne ended up with a stronger HMA and Violet.
So I'll say again, I'm with Dakid and Y-Girl on this. "Fucking around" may or may not count as polyamory, depending on the mindset of the person doing it and the relationship(s) they have and/or are forming. In our case, a one-night stand can be and is VERY polyamorous, because it has positive emotional implications for us as a couple, regardless of the what went on with the third party. If it becomes more than "just a fuck," then the polyamory extends to the 3rd party, I guess. lol THEY are now engaged in a polyamory-style relation, at some level, to be determined in time.
Such is how the world revolves, according to my perspective.
