Randall suggests that healthy sexual developement is helped by sexual information and sexual exploration during childhood. He points out that experimental deprivation of normal opportunities for sexual rehearsal play in primates produces adult lacking sexual competence and unable to rear their young properly.
This book is both brave and useful in calling attention to the fact that a relationship between a young person and an adult that includes a sexual element is not always traumatic and corrupting.
Young children do need protection, though not the current ones that overboard with interventions more brutal than heplful.
