Simple question

[Dingan]

If you want to learn about the relationship of endorphins in the scene, just do a Google search or use any of your favorite search engines -- Dogpile, Lyacos, etc. Just type in endorphins + spanking, and you will get several good pages of info to study. Some of it is simple and some is technical. I find it interesting that the subject has been actually studied, but hey, we scientists can be spankos also.
