Genuine intimacy of any sort in a relationship is guaranteed to keep that relationship interesting and fulfilling. That is probably one of the primary reasons why intimacy matters so much in a romantic relationship.
Intimacy can come in different forms. Of course the two most potent forms are emotional intimacy and physical intimacy, none of which is more important than the other. Emotional intimacy and physical intimacy complements each other.
But why does intimacy really matter so much in a relationship? We tend to take it so much for granted that over time we run the risk of first thinking that intimacy is just some novel feeling at the beginning of a relationship and then follows the behavior that ultimately undermine real intimacy.
Intimacy matters in a relationship because simply it creates the environment for real growth in the relationship and a higher level of mutually fulfilling experiences.
And that is what every relationship is about. Yes, there is the happiness, and the joy and the feelings of being loved or being emotionally secure, but in the end if we are not growing especially emotionally all of this could be for nothing.
So intimacy really matters in a relationship and it is important to understand how this intimacy paves the way for these other things that make our lives so much more meaningful.
For there to be real intimacy in a relationship, the masks have to come off. Of course we have our personal space that no one should be allowed to violate. But beyond this, masks are simply disguises that we hide behind.
There is always a natural tendency to be secretive or not be altogether open, even in an intimate relationship. The antidote to this natural tendency is to be deliberately intimate in our interactions.
This requires dropping the masks that you usually employ - the half-truths, the pretensions, the false emotions. As we move away from these we are more open to what is more real and what is more substantive. That is the beauty of real intimacy. It brings truth rather than pretense.
Real intimacy of course goes beyond physical intimacy and emotional intimacy. It addresses the question of how honest partners can be with each other while at the same time maintaining their personal space. It requires a much diminished level of fear.
If intimacy can cultivate this level of environment then the relationship can hardly do less than grow and provide a source of emotional security and joy.
That is why intimacy really matters in a relationship.
