Hi Tutti and Hubby,
Welcome to our forum.
A poly lifestyle, generally speaking, is a situation in which there are romantic connections between more than two persons, and all the people involved are aware of the whole situation and are okay with it. If the connections in question are more about recreational sex and romance doesn't much come into it, then it's swinging or a FWB situation.
Hope this answers your question, glad you're aboard.
Love means never having to say, "Put down that meat cleaver!"
