At the end of the day, we won't have much say in it.
I think teaching little children about relationship building and moral responsibilities at 5 years old is a great thing, and then it could lead naturally upto sexual awareness at an older age.
Believe me it is not just CHAVS ( define a CHAV! ) that have sex before they are 16. Parents who believe that most kids would not have sex before 16 if they weren't given the chance are deluded.
Proper education at home and in the school should include the consequences of early sex ( cervical cancer, underage pregnancies etc) the consequences of repeated abortions and about STIs .
HOWEVER I do believe the government make it too easy for kids to have babies with all the benefits that are thrown at single mothers. This should be addressed and the underage parents of the babies and their parents should have to fund matters if they choose to keep the babies. Not Joe public who pays for everything.
