The number one fear about joining the swinging lifestyle for most people is not contracting a sexually transmitted disease, but rather, it is the fear of meeting someone they know.
The reality is, many people will meet a friend or two over the years at different lifestyle clubs. We do remember a new couple who attended a party. They were at the club for their first lifestyle experience and were nervous of meeting someone they knew. As luck would have it on their first night out at a lifestyle club, they met their aunt and uncle at the club. Their aunt and uncle had been in the lifestyle for many years. It was a surprise for all concerned, but it went really well.
We have never seen any meeting between friends or family go bad. In fact the opposite is true. Most couples have a great deal of fun and opening up a new type of dialogue with their friends.
We have bumped into a few people we knew over the years and it is always fun. We certainly understand the fear, but your friends or family are in the lifestyle for the same reasons you are.
