Sex education should not be imparted earlier on. I think that teenagers have to reach a level of maturity before being talked to about sex. Sex education during puberty is appropriate. If we started talking about it earlier on then most of the class would either be disinterested or not take it as serious as it should be.
Even through in today's world sex is a common thing in movies whether it is an animated movie or a normal Hollywood movie or boll wood movie . Kids get corrupted due to this . But we still can't let the kids know because either they will not be interested or they will not understand . So, let them be innocent .
In today's world, there is so much sex in the media that kids will be exposed to it whether their parents like it or not. Kids should be taught about sex by trained professionals rather than seeing it first in pornographic movies or in unrealistic television sex scenes. A little knowledge goes a long way.
