If you're scared of being judged, then you won't share fully, and intimacy is lessened. The more vulnerable and naked you can be, the more you can test the other's acceptance and receiving. Being vulnerable involves risk, and trust helps us to take that risk. As a CSAT (certified sex addiction therapist), I am trained how to rebuild broken trust and address betrayal.
When you share your thoughts and feelings, and the other receives them, they are holding and embracing a part of you. When they feed back to you that which you have shared, both of you are then holding it together.
