Hello. First time writing here. I'm not sure whether I am an aspie or HFA, and I'm still not clear on the difference. What I do know is that in junior high, I liked to run around the yard carefully following the trajectory of seagull shadows while dodging obstacles. I don't have any recollection of anyone noticing what, in retrospect, would have been considered odd behavior for a teenager in what normally would be the most socially intense time in life. This and similar recollections, combined with a sense of familiarity when exposed to autistic people, lead me to my self-diagnosis, which was recently acknowledged by my mother, who happens to be a psychologist who has worked with autistic children (she had decided not to reveal this information until I asked her directly).
I've been happily married for 7 years, and we both have other lovers. It's exceptionally easy for us to be polyamorous, although many of our friends in the poly community struggle to varying degrees. I suspect that part of the reason I am poly may be related to my failure to absorb cultural norms as a child. In general, I have no gut reaction to taboos, and although I have learned many of societies rules, I have the ability to violate these rules at will without embarrassment (since the rules are merely informational and not programmed into my core). I consider these traits to be significant strengths and benefits gained as part of the autism package. Of course, life was more difficult prior to learning these rules.
My wife is not an aspie or autistic, but like me, she tends to question all the rules. For unknown reasons, she has never experienced jealousy.
My longest term relationship is with an autistic woman for about 20 years, and continues.
I do not consider polyamory to be a thing. I consider monogamy to be a thing. Polyamory is merely the absence of monogamy; that is, the natural condition that would exist if monogamy had never been invented. That's what polyamory means to me, though there are many other definitions.
Note that in using the term monogamy, I am ignoring correct etymology, and going with common usage, referring to an expressed or implied agreement to exclusivity of a sexual relationship. Indeed I only have one spouse at the moment, which is currently the maximum permitted by US law at the time of this writing.
