I don't agree with all of this. Some of what you mentioned falls under hiding your true nature. Suppose they ask? "Have you ever cheated on someone?" Are you suggesting someone lie about that? That's setting the stage for deceit that is a terrible habit to cultivate.

If something about your habits or your past would make your partner think twice about you if it came out, you shouldn't hide it from them if you want a long-term committed relationship. If they are THE ONE, they won't care.
