Swingers club

My boyfriend and I have agreed to giving the lifestyle a try, we’ve gotten pretty close to having a night with a couple but her boyfriend backed out before going back to their room. We’ve also tried meeting people online but other couples have been flakey when meeting up. We’ve spoken about going to a local swingers club and I would like to surprise my boyfriend next week for his birthday. We’ve spoken about what we would like and wouldn’t like, we also agreed on just soft swapping if we go for the first time to test the waters & if we would like to take it further than we’d be honest. But I will be honest I’m a little nervous, I’m not necessarily nervous about us going into the lifestyle but more about going to a club, I wonder if I would get shy or feel out of place, what should I wear, what is it like... if anybody has experience I would love to hear it, even just on the lifestyle it self, how has it changed your relationship?
