Generally speaking, it is normal for infants and children to have a psychological craving for intimate contact; many infants can’t live without people and always prefer to be held by their parents, which are normal psychological changes during development. However, some people have an abnormally strong desire for physical intimacy even after they have reached adulthood. This is a psychological problem and if it seriously affects their normal life, they should go to the psychiatric department of a hospital for counselling and treatment in a timely manner. We can therefore actually assume that it generally occurs in the adolescent or adult age group.
