Newsflash. 17 year old ARE going to look at each other in a sexual way. Nothing you say or do will ever change that. You can put the girls in burkas like the Taliban, guys will still get horny looking at them if they are the only girls around. I'm not sure what kind of brain washing you have been exposed to, but it must have been severe.
I can kind of see Fuzzy's point, partially, in that sense that enough kids are already sexually active enough in high school, and the school should NOT encourage it. I agree with Fuzzy 100% on that. Where I think Fuzzy is wrong is that I think the school should not actively discourage it either. Let kids make their own dating decisions, and maybe parents have some say too (or not... another topic for another thread). The school itself should not be directly involved in that decision on a policy level. The school should also accept that kids ARE dating and offer free condoms to students.
