try clubs such as fabrique, opera, or propaganda (here more student-girls less sluts)
expat-oriented bars 1171, 31/7, sorry babushka and many more (everything easy to google I think)
or already mentioned here hot dog bar (ex doug&marty's boar house, near metro kurskaya) - good place to have great slut.
funny places were you can find girls for Reviewee - real mccoy, tikki bar, tema bar etc.
good luck
