Some people think that the apex of intimacy requires an absolute lack of boundaries, secrets, or ambiguity. Though honesty is generally a good thing in any kind of relationship, there are still some things you should never tell your partner, no matter how close you are. There are just certain aspects of your life that are best left to your partner's imagination. For instance, from the early days of my husband's and my relationship, we wanted to keep an air of mystery about the things that happen in the bathroom. All we had to do was shout that word and the other person knew that door should remain closed.
