It included many behaviors outside the bedroom, most of which would not be noticed as BDSM by others. Examples include holding the door or chair and taking her coat. It was interesting to me how many women looked with obvious jealousy that I would help her with her coat in a restaurant. If men realized how women value these simple courtesies, I am sure that many more men would perform them.
I've done all of those things my whole life. I wouldn't consider that submissive behavior. That's just having good manners and being a gentleman.
