I do have to wonder why you're on a site dedicated to polyamory if you're not looking for relationships. I'll suggest that you'd be better looking on a swinger site or such.
I'm leaving the post on the boards because we may have some polyfolk who also have open relationships who may be interested in sexual escapades. I've moved it here to the personals because you spoke of what you're looking for (which, per the guidelines, means it belongs here).
When speaking of various forms of non-monogamy...it ain't poly if you're just fucking around.
While polyamory, open relationships, and swinging are all distinctly different approaches to non-monogamy, they are not mutually exlusive. Folks can, and some do, engage in more than one of them at a time--and it's all good.
