Hello Throuplelooking,
You might want to look for poly groups in your area, google "polyamory" with the name of your state, or nearest major city. Trying to find someone via a dating site can be quite difficult, it is better to meet people in meatspace, and strike up a platonic friendship with them. Then, later on, they may have a recommendation for you, or they themselves may evolve into something more than a platonic friendship. Of course, all of this takes time and patience, but it can pay off in the long run. In the meantime, keep reading and posting on this forum, and you will make many friends.
Sincerely,
Kevin T.
