We had the same thing happen, was at an office party by the boss, he had a hot tub. Wife was the first one naked and then me and then afew of the guys joined in with us.
We're heading to Bad Homburg the end of this month and will be visiting Taunus Therme for a few days of FKK. If you haven't been there, it's really a great place.
Can’t believe you know that place! I loved going there when I was stationed in Frankfurt! What a beautiful facility, although it’s now been 20 years since I was there. I loved the multiple wet and dry saunas, the eucalyptus room, and the long corridor leading outside that had 3very manner of water containers spraying, blaring, dripping, or throwing water on you. Like a trial by water!
I did a lot of business in Frankfurt, and I always looked for a place like that to go when not working (I spent a lot of time in Miami too and went to Haulover beach any chance I had). After my wife retired, I would take her with me on my overseas travel and she loves that place - that along with Zuiver in Amsterdam were her two favorite places.
I've seen multiple links to Swiss spas, but also found out ( which I didn't know) that Austrian spas are mandated by law to be nude?
I found this great link for Austrian therme, I'm going to have to go back to Austria! How-To guide for Nude Sauna Etiquette and Therme in Austria —
There was a section of a pier in Geneva that was nude, but we didn't see any coed nude spas or thermes nearby.
It looks like most of the Swiss references are to high-end hotel spas, although I remember reading stories on Literotica about a chinese couple who embark on a journey of exhibitionism by going to Swiss spas...
We have a hottub. Our freinds all know we are always naked in it. There is actually a sign posted on it "Nude Zone". We are always naked it in regardless of who joins us for a dip. Some friends eventually take off the threads while others have no interest, unfortunately.
I am friends with a couple locally who are naturist like me. Once in a while we get together for dinner. Another friend of mine will invite me over for a hot tub soak with her and her roommate a couple of times a month. Otherwise, I'm not very social.
Unfortunately, I was only nude with several friends together as a little kid. Since college all my shared nudity with friends has been one-on-one. But I liked being nude one-on-one with my friends in college and my 20s and the few times it happened in my 30s. I specifically said "shared nudity" because I've been nude in front of groups of friends who knows how many times throughout my life up until just before I turned 40.
