The article’s logic is flawed:
On one hand it says: “The last connections in the brain to mature are the pathways linking the emotional parts of the brain with the reasoning regions. Connections to and from the pleasure centers are also relatively weak, making it so much harder for many adolescents to resist sex.” Which means the brain of the adolescent is still incapable to make the right responses to the stimulus of sexual pleasures.
But on the other end it recommends: “Don’t narrow down options and shut out adolescents for whom abstinence is not a realistic choice.”.
The flaw is this:
Subjecting an adolescent to a stimulus without preparing it or waiting for the proper phase in its development and expecting it to commit error just the same, is the highest form of irresponsibility.
