Sexuality vs Orientation

I've been thinking more about sexuality versus sexual orientation. I've found that sexual orientation appears to be a social construction in the way that our sex is. Orientation suggests a single direction--a rigidity that I believe is found less often than expected when talking about human attraction.  These are the vocabulary words handed down to us.  In the way that our bodies are sometimes forced to commit to male or female, the same occurs with our sexualities because for some, it can be hard to imagine a world where words cannot define. These terms do not provide the prope scope to explain and define the sexual, emotional, or romantic experiences of humans. And for me, that is frustrating.  It's frustrating to see eyes roll when I mention being queer.  Once, somebody asked me if I wanted to be "special"--if I was "above just being bisexual"?  I choose to use some different words because I try to find the most specific language possible to describe my experience and my feelings at this point in my life.  It would do little justice to pick one over the other, as they provide little space for reflection and even self-doubt, which I find is the best prompt for internal reflection.
