This is an extremly intersting thread. I've had to read this several times and spend the night thinking about it.

I think it's important that a Master is calm and level headed. Safety is important. No matter how horny the Dom is he/she must always be able to evaluate any situation. This means for me that when I dominate a woman that I always have to hold my emotions back a bit as to not lose control. I'm a sadist. I would have no problems beating her to a pulp, but I know in my brain somewhere far back that it's important to see to her pleasure, (and safety) so I stop before there's any permanent damage. I think that does make me a bit emotionaly hampered. I have trouble opening up, and bursting out in emotion. I always hold myself back a bit. I doubt it started with me being dominant. I think I've always been like this.

In contrast being a slave means that you don't have responsibility in the same way. All a slave needs to do is follow orders, no matter what emotions they're displaying, and if they screw up their Master takes care of the punishment. They don't need to set limits for themselves.

In this situation I think slaves will have more easy access to emotions than Masters.
