Just FYI: Finding PG-13 (or R)-rated images to accompany a post on polyamory presents quite the challenge.
I have this friend. We'll call her Charlotte. Charlotte is one of my closest friends, actually - someone whom I've known for years and years, and who I trust enormously, like family. We met when she was single, and over the years I watched her date around, then find a long-term partner, then move in with him. One night, sitting at their kitchen table over sushi and wine, Charlotte and her partner told me - in the same tone of voice you'd use to tell someone about a cool new restaurant - about a party they'd gone to the other night where they'd both had sex with other people.
Oh, really?
