What Characteristics should a Dom/Master have?
A good Master needs to be strong and I don't mean muscles. It needs to be a mental strength, a fortitude that lets him be able to give orders and follow up to make sure that it is done. And be able to give out punishment as it is needed. Yet we also need to be able to have those moments where we need to have someone to break down to. Being able to just sit there and be held from time to time is the real strength that any person holds.
Also a good Master has to be able to read their slave. I know my little pet so well that she never has to use her safe words. I can read her body language so well that I know the difference that one more swat will bring tears of shear pain and that of being done for the session being done.
