When I go go a club I look for them. 5' tall, 85lbs with small tits. If no true spinners are around, I then look for very petite dancers. Now this doesn't mean that I sacrafice size for mileage. I also have favorites at the other end on the spectrum. 5'11" 150lbs. But given a choice I pick the litte ones.
Does this mean that I am living a child molester fantasy?


No, there are some small women that are definitely mature. You just get off on the fact that they are smaller versions of hot women. And a strip club is a good place for that because the guy lays back and the girl can be dominant (maybe THAT's where the kink comes for you), and more than anything the size disparity between the larger man and the smaller woman doesn't matter so much. If I was on top in missionary on such a petite thing, I'd always worry about smashing or overwhelming her. So, spinner on top for cowgirl is just the right play. Also, because you have had numerous pleasurable experiences like that, you also have developed a favorable association with it, so just the sight and anticipation of a VIP with a spinner might get you half-way there already.
