I include anything with feelings as polyamory. I think FWBs can qualify because feelings are involved. I think polyamory is most often a sub-category of open relationships, which include more things. Some poly relationships, however, aren't open, such as polyfidelity.
Open relationships, for me, include casual sex, anonymous sex and anything like that.
I don't think being polyamorous excludes having also casual sex. But if you only have casual sex outside of a single relationship, I don't think that's polyamorous. I think it's another form of non-monogamy. Poly requires being open to more than one relationship.
I think the map of non-monogamy is needed again! Here you go.
