I didnt try this format myself as it's is way too bitter sweet for me. but walked around and talked to some girls just to find out mostly for fun.
all girls were sober (not junkies). I guess Albanian.

Kurfürstenstrasse prices 2021
-----------
blowjob 40

BWC 50

sex in a so called sex cabin 60E+20E for the cabin = 80

sex in a hotel (one hour) 100E-120E depending on the girl
-----------

rather expensive prices in my opinion but at the same time Im glad that they can take that much as this job is probably the hardest in the world.
