There are plenty of us here who identify as queer in some fashion or are involved with queer folk of some variety. We also have plenty of folk who deal with mental illness/disability in our selves or partners. Personally speaking, nothing you've described strikes me as unusual in any fashion.
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.
