Did I Miss A Memo?

I started clubbing over 20 years ago, and went solidly up until about 8 years ago. I took a few years off but about 3 years ago started frequenting again. And I noticed a major change. I've been in clubs all over the US. In the '80's and '90's it seemed to be always the same. On a typical dance you might get a nipple brushed across the face occassionally, but everything was pretty much just a spectator sport. And I'm only speaking of the mainstream, topless clubs here. Of course there was always more fun to be had at the lesser-known underground clubs.
I quit regular clubbing for a couple years, and since returning, it seems that in every club, the expected behavior is touching is now allowed, if not encouraged. Again, some more than others, but now if you aren't sure, hands are usually placed there by the dancer. And this isn't just at local clubs, but clubs all over. Maybe some of you haven't noticed because the "change" happened over a period of time. But having stopped and then returned, it's still quite a nice change for me.
This may only pertain to those who've been clubbing for many years, but have you also noticed this? Do you think it's because the industry has become a lot more mainstream, and the occupation a little more accepted? Just curious as to your thoughts. (And please understand that this is NOT a complaint of any kind! It's a celebration!)
