If a child has a fear of falling in love, it is necessary to first determine whether there is a problem with the child’s sexual orientation, such as homosexual orientation of the population, the tendency to avoid love between the opposite sex; it is also necessary to explore the biological background that produces this phenomenon, such as whether the child’s developmental level of sex hormones is abnormal; and finally to explore whether the child has a psychological background of fear of falling in love. For example, some children have had sexual trauma as a child, such as being sexually abused, doing sexual games, or unintentionally witnessing their parents’ sexual behavior, etc., can have a subtle impact on a person’s sexual awareness and interaction with the opposite sex. People with psychiatric disorders can also develop relationship phobias, such as a neurosis called social phobia, where the core symptom of the patient is fear and avoidance of human interaction, especially with the opposite sex, and can even sweat and fidget. This negative experience and discomfort can be a hindrance to the patient’s normal relationships, and the truth is best clarified by the person themselves. This is where the surrounding population, especially a psychologist, is needed to dig into and psychologically assess the reasons why the child is having this psychological phenomenon.
