No doubt. I went to a public high school in a medium sized city. I can't even remember how many girls ended up pregnant during my 4 years in h.s. According to my younger sister, it only got worse the next 3 years. People (guys and girls) that I thought were highly intelligent and fairly moral people were having/fathering kids left and right. Our "sex ed" was a 30 minute video on STDs. We learned nothing about condoms, birth control, etc. Basically abstinence was stressed. A lot of schools in the Bible Belt are wary of discussing sex and stuff like that so they just say "don't do it." Needless to say that didn't work too well. Thanks to my parents being intelligent people, I knew all I needed to know looooong before I needed it.
But not everyone was so lucky. It's a fine line to walk but it needs to be walked if we're going to stop babies from having babies.
