polyamorist

plural polyamorists

1. An advocate or practitioner of polyamory.

   This lack of interest in multi-party marriage among polyamorists is particularly interesting given the fact that, as mentioned above, there is often a legal marriage between at least two of the partners in a polyfidelitous group.
