I would say it depends.... We all grew up in the same mono dominant society, and many of those terms are associated with mono mindsets. I find that if using a term seems to trigger a default mindset / emotional reaction, then I may try to use other terminology for my own sense of clarification.
Using the term my husband *could* be utilized as a form of ownership, but it also describes a legally recognized relationship. I would say only you can determine which you mean.
I, myself, have often wished to invent new words to more accurately describe poly. I tend to look at all relationships as "one individual who loves another individual (or more than one)" regardless of format - unless one is defining her / his self identity on the relationship. But that's all rather arduous to say.
