Stumbled across this probably a bit too late to be of use to you.
Haven`t tried Pasha in Munich. I understand Pascha is a chain of brothels with outlets in several major German cities:

I clubbed at FKK Sudfass Oase at Peter-Anders-Straße 4 in an industrial park in the west end distict of Pasing, easily accessible by S-Bahn. This was over a year ago. No great shakes. A bit pricier than FKK clubs elsewhere in Germany at 75 euros for a half hour plus a 55 Euro entry fee. Upsell for BBBJ. Small and cramped club but decent selection of ladies.
Bavaria has the reputation of being a bit prudish and limited for sex club options. FKK Colosseum at Gubener Straße 13 in Augsburg, about an hour from Munich by train, is the best option I`ve read about in the area:
www.colosseum-augsburg.de (caution-has sound).
Germany`s best clubs are in Berlin, Frankfurt and the Rhineland around Cologne and Dusseldorf. This is where you have to go to really experience what a paradise an FKK club can be. More at this thread:
