well... I think that it is more than just the physical touch of it all. No doubt that spanking warms the skin, and awakens nerve endings as well.. most likely resulting in becoming more sensitive to the slightest of touches. More importantly tho, I imagine that the spanking itself signifys a control/power feeling... depending on who you are of course the one inflicting... or the one receiving.

I don't have any experience in the area, tho I would love to claim that I did... and sometime I will
