No one type of intimacy should be held as more valid or vital than another. And relationships that are not "traditional" should not be seen as barring or lacking in intimacy because, well, they're not. Intimacy within non-traditional relationships is just one variation among many. It is as legitimate and nourishing as the intimacy of traditional marriage. So why not open up to unexpected experiences of intimacy? Why not accept the value of intimacy, no matter where it comes from? Why not spend more time seeking to be happy than worrying about being right?
Jenny Block says intimacy exists in many forms (even on one night stands).
