Why do some people love children?

There is many different theories about why some adults fantasize and having sex with children, some say its because the mind of the person believes he is the age (sexually speaking) of the children, so stays attracted to that age group, others like the innocence or see something most cannot imagine ever thinking about. If suffering from these unnatural desires, it would be best to visit a therapist or psychologist to discuss their problems, and to prevent them from hurting a child.
