Sex education in schools

What does everyone think sex ed should be like in schools? Personally I think it should actually educate, rather than aim to prevent sex from happening. Let's have people come out of sex ed with a good knowledge of sexual etiquette and the knowledge to please their partners. (Oh, this comes from someone whose school had abstinence only sex education in which it was taught that condoms with neither prevent disease nor pregnancy. I'm not making that up.)

this type of education should be left to the parents.  teaching something that may be considered 'right' or 'wrong' depending on one's religious upbringing shouldn't be handled in a public school.  if parents try to raise their kid with a 'sex is bad until you're married, and contraception is evil' mindset, and school's teaching them how to use a condom so you don't accidentally knock up little Suzie in the supply closet, you'll just end up with a confused kid.
