I remember getting a sex ed class from Planned Parenthood.  It was really weird.  They said we should discourage the term STD's because it was too stigmatizing and  instead say sexual transmitted infections (STIs).  That was an attempt to indoctrinate rather than educate.  

However, they did actually provide some actual value to abstinence education.  They talked about the different levels of intimate contact and a stopping point well short of "petting" so that things didn't get out of control.  That was actually solid advice to provide a different stopping point so that kids don't get to the "can I just put in the tip" thinking that can't result in STDs or pregnancy.
