Forcing your pet to be plugged is a wonderful way to assert your dominance in public settings. The covert nature of plugging him offers a path to expand your D/s FLR into any setting of your choice.

While he may be caged, hopefully it is well fitting and he isn't feeling those affects, unless aroused.

On the other hand, a plug cannot be ignored. It becomes a constant private reminder of the life you share. Your unforgiving invader representing your dominance and his submission. Which is perfect as the physical and mental affects are likely keeping him aroused and thus enhancing the effects of the cage. If he is chaste, but uncaged, he is likely tenting, providing you with a pleasant visual reminder of your affects upon him.

Regardless, the affects are magnified if you both insert and remove the plug. It is a humbling, humiliating, and deeply submissive act to expose himself to be penetrated by his dominant. Your goal is to stress that YOU are doing this to him, enjoying it, and the only one who is allowed to insert or remove that symbol of your dominance.
