I’ve visited Germany 3 times in the last 16 months and have to report that the FKK experience has deteriorated tremendously in quality while cost are on par with US.
I visited Oase and Sharks in Frankfurt, Samya and Mondial near Cologne, Artemis in Berlin and Atlantis in Munich.
While each club has attempted to refresh their ambiance the mood is strictly business and transactional , the ladies are unmotivated and greedy invariably promising much and delivering little with many upsells and surprises in the room.

The balance of beauty and charm seems to be disturbed by tacky attitude,  too much lipstick and new, lower educated class of Romanians that lack skills compared to previous generations.

After 20 or so encounters I must conclude that the new generation of providers is a lot less desirable so I discourage any readers from going unless you want to have the same experience I had.

If anyone had better luck please let me ‘now. I’ve just about had it with the red condoms (free on the house) and the ladies that feel entitled to 200 base ++++,

Nah, for that I can do much better at home

First of all, let me acknowledge I can see “Goodbone” is a highly experienced and well traveled member, and is due a lot of respect.

I am saddened to read that you’re disheartened with the FKKs. My experience is a little different and I would like to share.

I found my first FKK at Sharks in Frankfurt about three years ago. I was blown away with the entire experience and have revisited about four times a year since. I have been to Sharks, Oase and Palace in Frankfurt, Globe in Zurich and Sunshine in Munich. Every one of them have provided me with a fantastic time.

I realize your experience goes way deeper on time, but for me, the last three years have been consistent with seeing many of the same ladies and the “service” to be incredible. I realize your disgust is from a longer range of time, but for me, I can’t think of a better “pay-to-play” environment than the FKK experience.

I've been a customer at FKKs since probably 2010 or so when I started making regular business trips.  I think the first thing that severely hurt the scene was the 2017 "condom law" (not the real name) which outlawed any "unprotected" sexual activity in FKKs or brothels.  They also outlawed flat-rate clubs, called Partytreffs, where you paid a single fee and could have sex with as many girls as your plumbing could handle.  

Back in those days, sex could break out at any minute.  In the lounge areas, there would be BBBJs as a warm-up exercise.  In Partytreffs, spontaneous orgies would start at a moment's notice.  Some FKKs offered bareback sex ("AO" in German).  In all/most FKKs, BBBJs were expected.  The important thing is that the decision was left up to the provider and the customer.  The 2017 law killed most of this.  There are no longer spontaneous blow jobs in the lounge and the Partytreff scene is dead.  AO clubs still exist, but no bare sex of any kind happens in a public area.  

I used to really like Partytreffs.  The women tended to be older, but they loved sex.  The spontaneous BBBJs and orgies were spectacular.
