I don't give him paddlings to help him sleep or for stress relief on days when we have intercourse. Not fair to him. Frequently after a spanking for these reasons we will have sex or I ask to watch him relieve himself. On other days I ask if he masturbated recently. If he admits he has, I give him a few swats but delay the full spanking. If he doesn't admit it, that is his problem. If it is a disciplinary paddling, I don't ask. About half way through I have at times made him masturbate and then finished the swats. It seems to get his attention.
