I think that sex education should be taught in school districts where the majority of parents have no objection to it being taught -- sex, after all,
is as much an essential part of the human experience as food, drink, and sleep are... however, 4th Grade is WAY too early!
I'd say, teach it in a 9th Grade Health class -- the kids are 13 years old there, about to enter puberty, and they're at that age where they're
starting to naturally think about these things anyway. That way, you're addressing students' concerns, not forcing new ideas on little kids who
aren't ready for them...
Just my $0.02!


My first
sex education lesson was when i was 11 and of course we all giggled at a full naked lady, hearing the word "penis" etc but it helped me to develope
as a person.
