I have never been to a swingers club. Maybe other have and can chime in here. But, I thought that there was some etiquette when attending. For example, “No means no!” So, if the club you are considering has such ground rules, you could always suggest you go check it out, meet some new people, and see what it is like without the pressure of her ever taking her clothes off.
Also, I have never been as close as you are in convincing my wife to try someone else. So, take this advice with “a grain of salt.”
Good luck.
