Quoting MysticWitchKat:" Did you ever consider the fact that those kids are just telling their parents what they want to hear, ... [snip!] ... don't have 'sex' in high school. They engage in a lot of other risky sex behaviors which still are addressed better by sex ed."
Did you ever consider the fact that kids lie to their peers? LOTS of kids dont have sex but say they did due to the intense desire to be cool and fit in with lots of other kids that may or may not even be having sex.
It goes both ways.
Aside from education and teaching your kids about consequences, maturity and readiness, parents have to understand who the kids are hanging out with.
The culture of some communities and schools promotes sex and the culture in other communities discourages sex. Hopefully, I'll be able to keep kids i love in cultures that discourage sex.
