1. Definition and Relationship Changes: Blue confidante usually refers to male friends who have an intimate but non romantic relationship with a woman, and they have a deep friendship and mutual understanding. After two people have sexual intercourse, this pure friendship relationship often undergoes a qualitative change, possibly transforming into a lover, lover, or other more intimate but non pure friendship relationship.
2. Should we continue to be referred to as "blue confidants": Starting from the traditional definition of "blue confidants", once sexual intercourse occurs, simply calling them "blue confidants" may not be appropriate, as they emphasize intimate friendship that is not a sexual relationship. However, if both parties agree and are willing to maintain the original depth of friendship after sexual intercourse, and jointly accept this new relationship positioning, they can also choose to continue using the term "blue confidant" to describe each other, but this has gone beyond its traditional meaning.
3. New Relationship Definition: After engaging in sexual activity, two individuals may need to re-examine and redefine their relationship. This may mean that they need to communicate openly and understand each other's feelings and expectations in order to find a new, mutually acceptable relationship label. This new label may include "intimate partner", "special friend", "lover", etc., depending on the actual situation and common wishes of the two individuals.
