Good pointAlex, it is why I don't use physical punishment very often. First why take something we both love and make that a punishment. Second I know where she lives mentally and can do more with that then just pain will ever do.
Yes I am aware of mental abuse but that isn't what I do either, an example is that when she brings out the brat I may give her a spanking because it is what she wants, or if it is more then just being morgan I can have her put a cloths pin on her tongue, she hates that. I can stop being her Master till she can't stand that. All of these punishments effect a change but not from pain.
