Hello jsassy123,
You might want to start with some poly-friendly dating sites/apps, OKCupid and Feeld are two that I know of. Also check and see if there are any local poly groups in your area, google "polyamory" (and/or "ENM") with the name of your state and/or nearest major city. Finally, you can just get out there and meet people. Fringe events such as indie concerts, Ren Faires, sci-fi cons, BDSM munches and the like, will have more people who know of poly or at least will be open-minded about it. Even taking a class or joining a club, something that interests you, can result in a friendship that evolves into something more. You do have to be patient. Anyway, those are some ideas.
Regards,
Kevin T.
