I agree, 15 year old kids shouldn't be having sex.
Since we all have endured the powerful feelings of lust in our youth, it is imperative to have open conversations with children (both boys and girls) about sex and their bodies and wise choices. I am sure you have had those and your children would come to you.
But, unfortunately, many children do not have that safe environment and this may be their only answer to sexual abuse from a family member or family friend.
Those who have provided family values and security do not have to worry about the government policies regarding this. As you know, many laws and policies are made because some yahoo did something that was unspeakable. And when we see these laws we are bewildered that common sense did not prevail.
Keep writing and keep us thinking!
