FunCouple201

So my girlfriend and I have progressively been trying new things and have just come to the conclusion we would like to swing with another couple. We are wondering where should we go to find like minded couples? What is the proper way to go about this as we are very respectful and want to make sure we respect other couples and not offend. We are fun loving and want to share that with like minded individuals. Any information would be great. We thank you in advance.
