I think we're all always thinking on some level. Some more than others.
For me, I think I want this to be one of the best, if not the best, oral experiences a guy has ever had. I have fallen victim to the shallow, spasmodic slurp of a terrible blow job and thought for 2 years that they were an unpleasurable form of sex.
So whenever I meet with a guy, I am always naturally assuming that he has never had an amazing blow job before and so i am aiming to give him that. My immediate goal is to make it clear to him that I have the situation under control and that his penis is mine now, and I just do with it what I want until I'm finally ready to let him cum. I enjoy the submissiveness you can get out of a top when you're sucking him off. They become babys and just melt, figuratively and literally lol. I guess that what I'm thinking, I want him to melt, let go and give himself to the pleasures I'm going to give him, no matter how sensitive it may become, and then say wow when I'm down.
