I like this decription! There are a few of us here who seek the same or similar type of relationship. There is a discussion thread for "solo" people where we talk about our ideal situations and what we want. That is here: Solo poly people - what's your ideal?
Even though you think you are not technically poly, you are welcome to post there.
Personally, I don't think having casual, less committed relationships excludes us from identifying or considering what we practice as polyamory. But it's not the labels that are important, anyway.
