Threesome hook ups

Hey there,Probably a dumb question but here goes. So I love being with girls and love bi action - partner loves to watch and occasionally join in (with me mainly). We've found S&S balls perfect for this but know that this is not really good at swingers parties as I really don't want to play with a guy. I just like to play with the other side every now and then. We're looking for someone who knows what they're doing and I don't want to be with someone that is "bi curious" and has never been or played with a woman. Where does one find this elusive "unicorn"? Do they really exist and are there single or attached women who want full on 3somes with NSA? Just wondering how you go about organising all this without it being kinda awkward? Thanks - sorry for the rambling.....
