Dear R...,
first of all you have to feel free, to let your self belong to your master/dom completely. You have to enjoy serving him, pleasing him. Then it comes natural. Taken commands, rules, roles. Enjoying the rules, the role playing, offering both your body and your mind. Do not say I am "embarassed, I am not doing this", but "I am following you" in our erotic journey. Of course training is part of the "procedure", obedience is the key to achieve the training goal. Training goal might be everything, from learning how to react when being punished or to having a specific behaviour under some circumstances, or many other things...

Hope that this is an impulse for others to write their opinions, too.
Regards,
M....
