You will have a great time. Don't worry about being in the LS or not. Many people are and many are not. Lots of great people of all ages.
Lots of threads to peruse, but essentially you'll find a lot of wonderful people. some will have tops on, most in the pool will not. if you want to wear your top, wear it. if you don't, don't. no one pressures your. You don't have to be into lifestyle and they won't pressure you there either. Make friends on here, which makes it a little easier. honestly once you get there, just say hello to people. I had never considered myself social, but I always have a great time meeting new people at Temptation. Just relax and have fun. We're in our 40s, but have met couples from their 20s to 60s. Admittedly we are biased since we met there. Mark's been 8 times and I've been 4 times if that tells ya how much we like it. Hope that helps
