I'm 21. Growing up.. there were over 30 girls in my senior class that were pregnant. The senior class was only 107 people. That's mind blowing to me.
Of all my friends growing up, I was the only 'virgin' for the longest time. Of all my friends growing up I was the only that did NOT have a baby before the age of 21. I still don't have any kids, don't plan on having kids for a LONG time.
We never had sex education in my school. They never spoke to us about sex, or how to protect ourselves. We did have a local clinic that gave out condoms for free, and provided free birth control. You could go in there and get on birth control pills, or even get the shot for free. You didn't have to worry about them telling your parents, by law they couldn't tell them without your permission. So if your parents didn't allow it.. you could even hide it from them. I never understood why there were so many girls pregnant.
I don't think it is the school's responsibility to educate children/teenagers about sex. It is the PARENTS responsibility. When I turned 13 my mother and father sat me down and told me straight out what sex was, the dangers of not protecting myself, they told me about how difficult pregnancies can be, what it does to your body, about all the diseases I could catch. They also told me that they know they can not stop me if I want to have sex, but it was their wish that I wait until it is was with the right person. My mother told me that the minute I felt like I should start having sex to go directly to her and we would buy condoms and birth control pills.
She told me about how SHE got pregnant at the age of 18, and had me at 18. She went through 72 HOURS of labor with me. She told me how painful it was, and it scared the CRAP out of me. I definitely wasn't wanting any kids. I also saw how difficult things were for us growing up, we were so ding dang poor. There were many times that Christmas would come around and I'd get nothing under the tree, not because they didn't want to buy anything but because they couldn't afford it. *I* didn't want to be like that.
Between my mother being straight to the point and telling me up front, and seeing how we struggled because of the mistakes my mother made growing up. I made damn sure not to repeat the process.
I don't think parents can stop their kids from having sex. If they want to have sex they are going to have it. Parents can educate their kids, and help their kids protect themselves. Teenagers are also pretty rebellious. It helps to be upfront with them, and to tell them right out - "Look I know that I can't stop you if you REALLY want to do it, but here is what you should do and think about before you actually DO it.".
I'm proud of my mother and how she raised me. I'm damn proud of the fact that I was one of the few kids in my class who didn't get pregnant or married before I was out of my teens. I am 21, and I'm just starting college, but I AM going. I am not married, although, I am in a long term relationship (3 years so far), and we have lived together for two of those years. We don't want kids, and we are taking the necessary precautions to NOT get pregnant. Lord knows I am not the best person in the world, but I'm not that bad, and I'm constantly working to get better.
Parents need to get their butts involved with their children, educate, and LISTEN to their kids. It's good to talk to them about sex, but make sure to listen too. You'd be surprised what just listening can do.
