I will be visiting amsterdam soon from Chicago . This would be by 7th trip to Amsterdam. It always has been de wallen and been tired of it now,I always wanted a DFK ,seems no girls in de wallen provide dfk inspite of amount you pay .This year I realized may be germany can be given a try too . I heard a lot about Pascha in Colonge .Anyone has visited recently and if there are any other better options in AMS or Colonge .
If its pascha I was thinking of spending a night in colonge and visit pascha during evening . I will post about my trip soon , any good recommendations would be of great help .

DFK in the wallen is long gone.
Stlii possible in Amsterdam in both the Pijp and the SIngel,
and also possible in Alkmaar, if you like the window experience.

In the Cologne area, my favorite is still Bernd's.
I have made four trips this year, and will return again twice in September.
While talking to locals there, I have had very positive reviews of Samaya and Finca,
and have had positive reviews of a new bordello (not FKK) called Club Nylon.
I have no personal experience at any of these clubs, but the reputation and experience of the punters passing on this advice is beyond reproach.
I have no information on Pascha.
I have had many good trips to Babylon, just west of Cologne in Elsdorf, but no visits post-Corona.
