Elisabeth “Eli” Sheff is a polyamory expert. When she first heard about polyamorous relationships, back in the early ’90s, hardly anyone was talking about this stuff. But Sheff became fascinated, and for the past 30 years, she’s been studying the lives of kids who grew up in polyamorous families.  On this episode of “Modern Love,” Sheff tells the host Anna Martin about her personal and professional findings from decades of being immersed in polyamorous spaces. Plus, she has advice for people who are trying to figure out if being poly is right for them.  Subscribe today at nytimes.com/podcasts (http://nytimes.com/podcasts) or on Apple Podcasts and Spotify.
