1. You are not afraid to be (or look like) yourself.
According to psychologists, there can be imaginary and natural relationships. Social manners are used in imaginary relationships, and we use them to appear as though we came down from heaven.
In natural relationships, you are not shy or scared about being yourself and you know that your partner understands that you are not a robot and also wants to feel relaxed and at home.
You can walk around the house talking on the phone with unbuttoned pants, eat oranges in bed, and still feel that your loved one is absolutely okay with this.
