Try finding a swingers club in your area. Just being in a decent size city just searching "city name swingers club" should yield decent results. Alternatively if you start browsing local swingers subreddits you might be able to find lesser known clubs or events like hotel takeovers. I have been a local club few times and haven't participated much, but it is fun with the themes and skimpy clothing. As long as you aren't an asshole, they are usually very accepting of you having fun letting your suppressed freak flag fly.
Side note, highly recommend taking the BDSM test before going just so you know what you are into in case it falls in your lap the first time you go. Or you know what terms/labels you want to avoid.
