Generally, I don't think so, although that is probably a component of many relationships (intimate relationships?). For example, I'm sure that many men and women will surficially agree with their spouse on "hot button" issues, while secretly not agreeing at all. Also, many will hide from their spouse certain events of their past, or certain kinky fantasies, for fear of angering, disgusting, or alienating their mate.
But, for the most part, one cannot have a satisfying intimate relationship without a fair amount of intimate and honest disclosure.
