How can children find the adult body as anything other than unappealing at best, or disgusting at worst? With its hair, its odor, it's various swelling protuberances, its secretions, etc.
Anyone who has had the pleasure of being with young children knows how inquisitive children can be. Physical attraction may not be the right description, but physical interest there certainly may be. Those very things which Enigma describes as unattractive features, may be fascinating for some children. And very pleasant it is to be on the receiving end of that interest.
