I vote no simply because the gift giver (subs) are the ones who get the reward. The affect it has on the Dom is just another result. Submissives aren't submissive for the sake of somebody else. They are submissive because of the the perks that come with submission. because I guarantee that if a submissive didn't get any joy out of being a sub then she ouldn't be one, even if he loved one wished it so. It's sort of like a guy buying a flat screen TV 'for the family' when we all know who it's really for.
