My experiences with a polyamorous woman (no, not that kind of experiences):
Back when I was in high school, there was this girl who went to a different high school but sometimes showed up at mine to... yeah... play board games.
She was called "Fish" because she smelled bad. She was tall, lanky and had greasy hair and bad acne. From what I heard, she came from a somewhat strange family, where the dad and her brother were apparently OK guys but she, her sister and their mom were wackos who really disliked washing themselves.
Fast forward to some 8 years after I've graduated high school. Fish shows up in my new home town and starts working at this bar that I'm a regular at. She has turned into one hefty mama and grown a gigantic horse ass. She has lost the bad smell and most of the acne though.
Fish kinda keeps her distance from me, even though I know here from "before". After a while, I hear from these guys I know that she's hitting pretty heavily on them, despite being married to a bald beardo of guy. The I start hearing all sorts of weird things: Apparently Fish and Bald Beardo are involved in the polyamory/swingers scene in another town.
After about 6 months, shit hits the fan and Fish is fired from the bar because it is discovered that she's stolen about $5000 worth of money from the safe. She appears in court and tries to plead temporary insanity by claiming that she had a miscarriage at the time. Eventually, she pleads guilty to theft, but a lesser amount than what had actually been stolen. The bar decides not to take it to a higher court and she is formally banned for life.
After this she has a kid with Baldo Beardo, then divorces him. She starts trolling dating sites, playing up the "single mom in need of a man" angle. She also has a "dating blog" where she reviews dates and speaks ill of those who don't measure up to her standards.
I haven't checked in a while, but she used to have a fairly active social media presence. You see, she's has been into LARPing for a long time and if you search for (Fish's actual first name) + LARP, one of the top results is a pic of Fish dressed up as a classy half-orc prostitute or whatever. She's tried her hand at modelling, so there is quite an assortment of pics available on the net where she looks like absolute trash.
To sum it all up: She's bangable, if you are into chunky asses, greasy hair and broads who will shit talk you after you've boned them.
