Remember a time, possibly before the InterWeb appeared, when you felt all alone in This Thing We Do? One of the first long discussions I had with people here was trying to figure out, by Nature or Nurture, why such a silly thing as adult spanking could be so erotically charged. We came to conclusions good enough, but one of the things that came up was how we might have been "imprinted" as Little Dudes Figuring Things Out.
It can be a complex mater, but I do tend to think that exposure to such images as these must have had some effect...
Well, in any case, we certainly would have had our particular proclivities revealed to us!
