Wife, why? I know the guy is sub, and the commander is in control, but choosing to give him the title of wife for a reason like that feels kind of icky.
Edit: For you guys that are flaming me. The fact that the guy is made to bare the female title in a married relation, comes with some rather controversial connotations. Namely that the guy is filling a dated gender role that wives had as their husband's accessory, as well as other roles that should have died out a couple decades ago, if not even earlier. This is why I'm feeling a bit icky about how the guy is being addressed and treated, granted the guy is practically a self-insert with how much of a blank canvas he is, but I digress.
