Is Polyamory Covered Under Sexual Orientation?

I've yet to hear a scenario where someone had felt major discrimination for being polyamorous. Most people, I mean, it's such a personal nature of things like they keep quiet about it. There are a lot of people who I haven't shared this with or and and and I don't proselytize it as much as maybe I know some people do. That's both a personal choice, but at the same time, I do covet what it would be like to just live openly and normally.
