You need to buy the pole-dance platform and may be lucky that one of the girls will use it,I never got this to work in my playtrough. It works fine in studio, though.
MY post on discord:
I never used the cheat for stats or desires. Just know, the girls have hidden desires, that go regularly up (eat, sleep, wash, toilet, fun,...). Every now and then the girls decide what to do, mostly following those values. They only look around in a certain area (range 100, whatever unit,... I don't know) and then go there. When you build your place, you want to observe, which Installations are used the most, those should be in the corners. Then you place the fun stuff (pole, dance stage, plushy, cat,...) between those to make them pass it often. That increases the chances, that they decide for those at the right moment. When they are outside in the wilds or just in a room without fun stuff and decide for fun, they just play with a stick in the mud ... Just an edited example:
Additionally the trait
'child at heart' will help as well.
