Hi there
There is no such thing as parlours in Glasgow, there used to be but they were all closed down a few years ago. Glasgow city council has a low tolerance for the sex industry, even lap dancing clubs are only allowed to go topless NOT nude. They also don't put up with 2 girls + working from the same flat.
Edinburgh is much more relaxed, lap dancing clubs you can go full nude and the saunas in Edinburgh do still operate HOWEVER there has been serious issues lately and several have been raided and closed down so if your considering sauna work, now is not the time, not in Edinburgh anyway.
