Teaching kids about reproduction is one thing - and I agree that they need to learn it a lot better - but you and FranPam are suggesting teaching them about lovemaking which is something else entirely! wow!
Seriously, are you saying "sex education" in schools should include how to pleasure your partner and other intimate things?
As openminded as I am, I'd have to disagree completely. I'm 100% for teaching kids about reproduction and safe sex at the appropriate age, but I don't think grade school, middle school or high school is the place to be teaching how to have pleasurable/successful sexual relations with your partner.
Save that for the college-level human sexuality courses - which do exist.
