Sex education failure

It is so sad to see girls posting things like "he didn't cum I can't believe I'm pregnant" or "how am I pregnant he didn't cum / he pulled out" and us grown ass women will attack them with things like "you shouldn't have sex if you don't know that you could get pregnant from precum" or "if you are not responsible or can't afford a child you shouldn't have sex". It's not right while of course I know having unprotected sex at ANY age unless you are trying to convince or in a relationship/marriage is irresponsible because you are risking a lot more than a pregnancy. And just because there are many women on here who have been trying for years to conceive and find it unfair does that really give any of us the right to attack someone who made a mistake. They have options and so do we. Where I do find fault is in these young girls parents and the school system sex Ed is underrated and not taught young enough. Most place don't introduce sexual education until the 10th and 11th grade that's between 15 and 17 years old. But children are starting to act in sexual activities that they don't understand as young as 7- 8 years old. Now I know we don't want to believe that but it's true. And parents needs to take accountability and teach their children at home. How do you feel? How do you introduce sex ed to your children?
