Reading posts in the Life Stories and Blogs section is a great way to get a sense of the wide range of ways people are living as poly. It's a lot more balanced than reading in the Poly Relationships section, which tends to focus on problems. The sites that GG suggested are also good. It may be easier for people to offer you advice after you've developed your thinking on the topic to the point where you can ask concrete questions.
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.
