1. Girlfriends may touch on privacy, but it is usually done on the basis of mutual consent, trust, and respect. They may share some personal and intimate topics due to their close relationship, such as emotional experiences, family conflicts, etc.
2. Crossing the boundaries of privacy varies from person to person, and girlfriends need to clarify each other's comfort zones to avoid unintentionally infringing on each other's privacy. Respecting each other's wishes and boundaries is the key to maintaining a healthy best friend relationship.
Sometimes, intimate contact between girlfriends may involve sensitive topics such as sexual orientation, physical issues, etc. In these situations, it is even more important to handle them with caution, ensuring that communication is supportive and non judgmental to avoid causing harm to the other party.
