There are two basic ways of training a submissive or a slave.
They can be trained by using punishment or using Pleasure Training. 

     Training using punishment has been the method of choice for as long as men have had slaves.  The can be trained knowing that breaking a rule of the Master or not following his will will result in punishment.  Slaves are often punished by spanking, tying the slave and causing pain or depriving the slave of something. 
     Some of the things that slaves are denied include the removing the ability to orgasm and enjoy their bodies for a time or as a condition of slavery are told they cannot speak or only under certain circumstances are they permitted to do so.
There are many forms of punishment including piercing, bruising with paddles or floggers etc.. Some of these can be fun to do and may be fun for the slave as well.
     Many slaves push the edge of a Masters will and the rules he has set to provoke the Master into punishing them.  Women have a basic need to submit it is hard wired into them some men need this form of release as well. I have helped to train many men both as Masters and slaves as well as transvestites to enjoy it.
     The more intelligent and successful the woman the more likely she is to want to be controlled to have the awful freedom of choice removed at least temporarily in order to be able to relax and unwind from the stress of daily living and having to make the decisions.
