I found an interesting study done on intimate couples:  The Role of Intimate Identities and Communication Styles in Couple Functioning (http://www.thefreelibrary.com/The+Role+of+Intimate+Identities+and+Communication+Styles+in+Couple...-a0143064815)

Within the content of the report, the following observation was made:  the extent to which different communication styles were linked to relationship functioning was expected to vary depending on the relative importance of individuals' sexual self relative to how much they valued their self-in-relationship. We suggested that the relative commitment an individual had to their intimate and sexual selves would ultimately affect the level of satisfaction in the relationship by influencing the responses chosen in response to sexual versus general dilemmas

So, how a person sees himself in a relationship determines the value of  communication within any given relationship.

OK.... so how does this translate for the adoptee who, as a child, was not allowed to discuss the most intimate of personal needs (finding Mommy and Daddy) with the adoptive parents? 

Is it possible the need to keep quiet secrets in certain family-dynamics keeps sexual dysfunction alive in later-years?
