Yes, they do, but unfortunately the trend is to stick with 'abstinence only' education. Abstinence only sometimes gets to simple, as in not even talking to the students about the consequences of having sex.
As a parent I still believe it is up to me to teach my children what I want them to know. But I ended up becoming a grandma to my 19 year old's baby. We had countless talks about using condoms, I even bought them for him. But, and this is another important point, teenagers feel invincible, nothing out there can hurt them. All the bad stuff happens only to other people.
It's simply a part of being a teenager to think and feel that way, and can not be overcome by anything.
So until we all recognize that, there is going to be a long hard road of teen pregnancies, teen STD's and and other complications ahead of us.
