Chastity and orgasm denial discussion

It took some time to work out how to get my husband to reliably submit to punishment. The issue was that while he craves it and needs it to improve his behavior, he is actually afraid of pain. When he knows he has done something wrong, he struggles with letting me put on his restraint devices for the correction. He truly wants it and will eventually give in, but I prefer doing it when I am ready rather than waiting for him. Punishment always goes to his erect cock pulled out behind him. Perhaps someone can explain why I feel this is necessary; it is simply the method that works best for me because it makes me feel so powerful. Now that he wears chastity, though, it becomes simple. With the teasing I give him, by week’s end he is desperate for his “release and relief”. This is only available once he is secured in his punishment position. The release comes with a small whip (usually requiring around 20 strokes). If correction is needed first, the medium whip can be used. For major infractions I use the severe whip and withhold the release; increasingly desperate for that release, he submits to his restraints daily, receiving punishment but no relief until I feel he has learned his lesson.
