My submissive has known me for awhile but does he really know me? Can he make educated guesses based on what he thinks I like, or is he just going to get continually kicked in the balls because he doesn't know the answers?

As the questions progress I realize that he doesn't know a lot. I'm not even referring to me. This dumbass doesn't even know the difference between a city, state, country, nor continent. I can't make this up. This is an adult. He should know. Since he doesn't I will just have to figure out a way to teach him and make him remember.
