One of my best friends in high school accidentally found out that her parents were swingers when she was 15. She also found their "toy chest". She was seriously creeped out but grew up just fine and has a great relationship with them.
Me, 30ish bi female, been doing solo poly for roughly 5 years. Gia, Clay, and Pike, my partners. Davis, ex/friend/"it's complicated." Eric, Gia's husband. Bee, Gia and Eric's toddler.
