Strippers were entertaining when I turned 18.

Waste of money. Why spend money on some dancer when you can basically have your girlfriend future wife do it later? For free even? Because she WANTS to? I haven't been to one or know of any of my friends who even had one (and this was when I was living in Las Vegas).

IMO the grinding on you while you just sit there is not a big deal but when you start going at it grinding with them, then it's not good. Feeling up is bad as well.

Honestly treat her like an actual stripper...basically you sit there passively and do nothing. I find no harm in just that.
