Sara Canton had been with her boyfriend, Tim, for four years when he proposed something she didn't expect. "I want to be in an open relationship," he said timidly. "A lot of our friends are doing it, and I think it could be good for us."
Sara wasn't totally opposed to the idea. It was 2012, and many of her Bay Area-dwelling peers, some of them married, had hopped on the open relationship bandwagon. A kid's yoga teacher, Sara considered herself an open-minded free spirit, so she agreed to give it a try. "Something felt off, but I guess I just decided it was OK. People in our community were doing it, and I really didn't want to lose Tim. When it came down to it, it felt like a no-brainer."
