But how young? I agree that parents should take more responsibility in teaching their children about sex....not just the reproductive system and STD's. I had a former student (now 20 yrs old) tell me that after she and her boyfriend had sex for the first time, she asked him how he knew what to do, both of them being virgins. He told her that he googled it. How sad is that? I mean, he could have gotten loads of great techniques, but where would one even begin if not at least given some type of introduction?
