It really depends ...
Some men who are in high powered jobs and making decissions (having total power) all day at work enjoy being able to come home and not have to make any decissions. This actually is a way for them to relax from the streeses of there day job.
Some people are and always will be submissive. They enjoy not having to make decissions etc. These people normally choose a dominant partner.
If the person your talking about is the first kind then changing him could lead to him becoming stressed out and actually getting helth related stress problems.
If the person your talking about is the second kind you may need to order him to take charge for a certain amount of time each day.
