What do you wish you learned in sex ed?

I will soon be creating a proposal for the Clinton Global Initiative University for Planned Parenthood on a new approach toward comprehensive sex education.  I would like to take advantage of my recent spike in readership to ask all of you–what do you wish you had been taught in sex ed?

some examples of things I will be including are:

• consent, consent, consent.
• a discussion of virginity and what it means with regard to how teens approach sex today.
• safer sex strategies, including proper use of dental dams, the HPV vaccine, and emergency contraception
• exploration and sexual pleasure
• masturbation as a low-risk alternative to partnered sex (plus other low-risk partner activities like kissing/mutual masturbation, etc)
