I come from a country where sex ed does not exist in schools. My country is very heavily religion centred so any mention of sex in schools or families is seen as tabboo, unless you discuss with your friends. It's sad. And you can really and totally say "they shouldn't have done it" but my country has the highest teen pregnancies in the continent yet no one does anything to fix the problem.
So many young girls date manipulating men that are in their late 20's-30's and no adult in their life helps them out or saves them from predators. So many young couples never truly inform themselves about safe intercourse but instead talk to friends who did it before and "take their advice". Many young moms ans dads drop out. Many. Too many. (I had 2 teen moms in my class. Both dropped out).
It's so easy to judge, but the situation varries from person to person. You don't know of the girl is stuck in an emotionally abusive relationship with the baby daddy. You don't know if the family is religious and cares about old traditions. You don't know is the condom broke during what the couple thought was a safe intercourse. Sex is healthy, and if you have a loving and careful partner, it shouldn't be an issue. But shit happends.
Most kids aren't taught about the menstrual cycle as teenagers EITHER. Mothers don't talk with their daughters. Schools don't even teach the reproductive organs. Ignorance is everywhere. But it's sooooo easy to judge. Why not help and support people in need? Yes, it happend. If they can get an abortion, then great! If they can't, that's great too! Support them...help them finish their studies...It's not easy and you don't know their story.
