While I agree with you to an extent, there are shortcomings in leaving it all to parents. There are some parents who will only educate about abstinence which is great unless their teenagers don't abstain and don't understand about safer choices, then you are just another teenage pregnancy statistic. Those are the children who learn about sex from other teens and then the internet and porn, which in my opinion is worse than an open honest child-appropriate comversation. If parents dont ever talk to their children about their bodies and when they are older about sex, those children don't recognise sexual abuse is wrong and wont speak out.
