In my opinion a subject that shouldn't be taught in school anymore. My reason for saying this is that all it is is a scare tactic that teaches a load of bullshit like condoms fail 90% of the time, and that if you have sex you will get an STD no matter what. Its just a scare tactic to scare people into living a life of abstinence(although there's nothing wrong with wanting to be abstinent.)
In my opinion when it comes to sex, it should be taught at home by parents to their children, because in all honesty, sex is a very personal and spiritual thing that shouldn't be taught through diagrams and false statistics.
We shouldn't have sex ed in school anymore because now, it's nothing but a huge scare tactic about STDs and Pregnancy. Instead sex should be taught at home by the parents. And listen parents, it may be easy to leave it up to the school to teach your children about sex, but it's better to do it at home, because you don't know who is teaching your kids, it could be a person who knows very little about it, a person who has a bad opinion of it, or even a complete pervert.
