We have practiced punishment spanking for over 25 years. It started as erotic spanking and great sex after, but evolved into an very effective way for my wife to maintain her control over me.
We live in a FLH and she always has the final word, makes all the decisions, controls our finances and social life. My overall responsibility is to serve her wants, desires and expectations. We evolved into this female led lifestyle as a result of my convincing her how much better our relationship would be if she took complete control. After many conversations she eventually embraced the lifestyle. In many ways it dovetails with her personality.
One partner cannot "be in charge" unless there are consequences for the other partner for not submitting or complying to the dominate. We had already been involved with erotic fun spanking (of only me), so it was a seamless to move over to "serious" corporal punishment. This change only came about after we talked a number of times and reached a mutual agreement. My wife insisted that, if we were going to go this higher level, that there would be no more erotic spanking secessions, only corrective. The catalyst for initiating a secession could not be frivolous, but serious as far as she was concerned. One of the main differences in going forward, was the spankings would have to really "hurt" in order to impress me the error of my ways. There needed to be a lingering impression (redness) to remind me that I failed her in some important way. I would also have to be restrained on the bed to keep me from trying to run away when it became very painful, but she felt she wasn't finished administering the spanking. Also, there would be no sexual component to punishment spankings. We might go for 5-7 days after a secession without me allowed any release. This was to drive home the point that the spanking wasn't for fun, but to try to bring about positive change in my behavior. To be honest, I have become a much more responsible husband as the result of her guidance, knowing that she has the spanking available to always back her up.
Usually for 3+ days after a serious punishment session, going to work proves to be very uncomfortable.
