Bruh!

One of the safest things to do is to do search of any and all swing lifestyle venues in your area like the clubs, retreats, resorts ect. In some communities the lifestyle folks have regular places where they frequent like specific bar and grills, hotels, clubs ect.
Women in the lifestyle low key advertise their status that they are on the hunt for that bbc. You can look for QOS symbol on her jewelry and accessories. You can also pay close attention to the choosing signals that she is sending you by looking at you and giving you the eye while her man is sitting right next to her. Nowadays is the guy isn't getting totally offended by her looking at you then there's a good chance that they are a lifestyle couple.
Send them a ******* and see if they will come over to you. If they come over to you, then you can say some like: "hi there, you guys look like a fun couple, are you guys polyamorous or in the lifestyle" ? If they are not in the lifestyle they will find the fact that you sent them a ******* weird and will likely blow you off after thanking you but if they are in the lifestyle then they will appreciate the gesture and walk over and be social with you.
