Is there a link between being spanked as a child and having a spanking fetish as an adult?

I think there is a link based on my experience and those I've discussed this with. We all experience different physical sensation growing up, and some stick in our brain. We may not have liked the immediate pain of a spanking as a child, but there are other feelings involved that we may be attracted to. The brain releases certain pleasurable or protective hormones when it feels the body is under attack or is merely touched, and it is possible to want or become addicted to the hormones. One may like the feeling of riding a roller coaster, which explains the need to go out of one's way to drive over a small highly-curved bridge called "thrill hill."
