Helping Husband See That Chastity Is More Than Just Sex

My husband has voiced his interest in being put into chastity on several occasions over time. I plan to surprise him with it within a few days. However, I understand that even though he said before that he wanted this experience, the key is for him to realize that it isn’t solely about sex or role-playing. It must be done properly if we proceed, meaning he needs to attend to my requirements and so on. Since he possesses an alpha male personality, breaking him in will require effort. Do you have any suggestions for demonstrating from day one how things will operate? I could use some advice since dominance doesn’t come naturally to me. Thank you. Any tips specifically regarding the first week (which is likely going to be the most difficult)?
