You're welcome.
There are a zillion other little things that can help you feel submission. Just keep an eye out for them. Things like having you wait to sit at a restaurant until he tells you to, or ordering your food for you. When shopping if you were to keep to one side, or slightly behind, or whatever he desires. When watching TV if you were to sit on the floor next to his feet. I know a couple that enjoys her sleeping on the floor next to his bed. I asked her about it, and she said that she wants to be lower than him, and that helps her fill that need.
Be creative, have fun, and communicate. I think you will find things will naturally fall into place for both of you.
