Best Way to Find 3some Partner

I guess this might sound kind of weird, and I suppose in a certain sense, it is kind of weird. But I am trying to figure out the best way to find a partner for a threesome. Not two partners for a threesome, but rather just a single female that is willing to join in with me and my girlfriend for a night of fun. We have always been kind of sexually adventurous but this is probably the wildest thing we’ve thought about doing. I am posting a looking for 3some advertisement on this one site, but I am not sure if it will draw much attention or if I will get anyone to respond to it.

There has to be a somewhat easy to way to get the message out to potentially interested people that you are looking to have a threesome. It is not like we want to go to a swinger party and meet someone there, because we’re not swingers and have no experience in this type of thing. Not that we rule out the possibility of becoming a swinger one day, but that’s not where we are at right now. Instead, we’re looking for maybe someone who has never had a threesome before, so that we don’t feel awkward in the situation.

I don’t know if that would necessarily make it awkward, but the set of expectations would be different than if it was the first time for all 3 of us. I guess I am putting too much thought into this, and I do not want to burden the process with a lot of constraints, because if that becomes the case, then it is doubtful we will ever find anyone to join us. And that would be a shame because I think this is something we really want to try.
