hmmm.. no others have an opinion to offer here on this?
Some relish those marks with pride!
For me, when I dom I like the spanking but i agree that there needs to be more than just a hand, a paddle, a stiff hairbrush, mabbe even a leather belt. You know like you got a spanking with when you were young. Ant the idea of a progressive red mark is great. It should stay on until it is removed or the user logs out and back in.
