My (29m) wi(F29)e and I enjoy going to a lifestyle resort here in Ontario Canada once a year. We are monogamous ourselves, but we love the vibe and enjoy being able to be exhibitionists and voyeurs, meet sexually open people, and overall enjoy the amenities.

I am wondering if there any symbols or colours we can have on ourselves that indicate we aren't down to swap with others? Kinda like a stoplight party, but generally known within the lifestyle?

We've had a few instances where we are enjoying talking to people, but once they find out we don't swap they lose interest immediately. I don't want to waste our or other people's time, so if there was some way to visually indicate limits it would be handy.
