Explaining my poly tribe can be complicated. I've only ever had one monogamous relationship. It just doesn't work for me ideologically to promise to limit the possibilities of current or future relationships.
I raised my (and others') children in open polyamory. In fact most of the poly social groups I've been involved with are child friendly... bbqs, meeting at the park or pizza parlor, etc. It's helpful for kids to interact with others so they have a wider view of the world (and allies) and are not easily shamed or terrorized by disapproving bystanders.
In the past I have lived in a house of my own and had lovers, usually submissive, who moved in with me. At the current time, I have three primary partners who live nearby but separately. With each of them, I have a set of shared partners as well.
I share a house in a suburb south of Portland with my lesbian lover (approx 3 yrs). This is the house she grew up in. A friend and playmate of ours is a roommate. We also have a shared lover who lives just across the border in Washington with her husband and children and she comes every other weds and stays over night with us. (On the other weds, her husband overnights with his lover.) I frequently schedule group dates or "parties" with lovers, playmates at this house. My dogs live there because of the big yard.
I also share an apt in a suburb east of Portland with another primary (1 yr). (We tried living all together but they didn't get along and are civil to each other but not friendly... not jealousy issues, just general personality conflicts. They are very different from each other and speak to different sides of me. They are very protective of my other relationships.) We share this apt with my adult son (monog), his gf (poly) and my granddaughter.
My third primary (3 yrs) has an apt downtown and prefers to live alone. Altho this is ironic as the cute tiny apt usually has at least one "couch surfing" lover most of the time. We don't have a set schedule to see each other but we travel together, can end up in any house, bed, whatever together and share literally a dozen lovers, playmates, fwb and he has twice that of his own. Sometimes what we do when we get together is make a list of people we worry we have been ignoring. And make plans to see them.
Interestingly, the thing that makes it impossible for us to all live together like I have in the past is a combination of politics, sexual identity, and communication styles.
