All that has been answered is good advice from those that know, or at least think they know. Being a non sadist, I can give you adivce in one word, that applies to anything or any method that you might think of or want to apply to your relationship, and that one word, is PATIENCE. You have to have patience when dealing with a sub/slave in any actions. Your descisions on punishments have to deal with the serverity of the infractions. Some might warrent server punishments, while others may not. Your satisfaction comes from the idea that you rule, and your words are to be obeyed. Now I condesnse this by saying that the word were ones that could be obeyed, one needs to give a sub/slave an out, something that can be achieved without compromising both positions. With this said, I hope that you find a way that works for you, since the ways of others, are not always compatible with what YOU want out of the relationship.
