A spanked wife is a happy wife. I have no doubt there are many who wouldn't understand that sentence. But those wives out there who are loved by their husbands, and spanked by their husbands, understand the dynamics.
If there's something my wife knows she shouldn't be doing and keeps getting away with it then she begins to feel that I don't care or love her. If I did care and love her then I'd take care of her behavior. For those in the lifestyle it makes perfect sense but for others it's strange. From time to time I even get email from spankee's who are only into spanking because they LIKE it or use it as stress release. My answer to them is, "Good for you."
