Has he told you why?

You will have to decide ultimately (just as many of us do with other things) if the desire for it is stronger than your desire for his dominion.

No one is forcing you when you still have the will to choose.

Perhaps he has an extreme distaste for such things, perhaps he is uncomfortable with what desires such things may invoke within him.

Is it possible he is simpley testing your submission to his will by denial of that which you desire to see how you may respond?
