C.P.
You've gotten a lot of great advice! I don't envy you and certainly cannot relate, as I have 2 girls, ages 2 & 4. What is concerning is your husband's attitude. The most important thing for this situation to have a positive impact on your son, is that you and your husband agree to the punishment and talk to him together and openly. Without your husband's support and assistance, your son will continue to do this. I think I would talk to your husband quickly about having a "united front" and what needs to be discussed with your son on this delicate topic, and how it needs to be approached. Your husband needs to understand how important it is that he supports your actions, so that your son will take heart. Best of luck to you.
