I must admit, I have a similar problem. Much as I enjoy the dom aspect (I'm a switch, I do both), I'm too "nice" to be very convincing at it! I think a lot of the confidence will come from practice and experience. You can help to try and bring out his dominant desires by inspiring him - if resisting him will make him shout at you, maybe that is a good way to encourage him to be firmer. Or maybe that doesn't work so well, and you should be as obedient as possible in order to instill confidence that he can tell you to do whatever he wants.
