Sexual promiscuity in the adolescent has been commonly linked to suboptimal parental attachment. A child who has developed an insecure attachment template will incorporate any aversive sexual experience into his own sexual template when this comes online. Adolescence is the time when the child makes preparation for adulthood through behavioural practice and experimentation. At adolescence, the brain has reached its adult capacity, and so it starts to disorganize and reorganize itself, and has a neural growth spurt, particularly in the prefrontal cortex. By the age of six, the brain is around 95% of its adult size when the next important growth spurt occurs in the right brain. Sex protects the child from isolation so that the child is protected in the future. Sexual activity between children becomes abusive when it involves emotional and physical abuse, using coercion by employing threats, bribes, or promises of special attention in order to maintain the secret.
