At the time I didn't understand why they were so against it and as a result I was also scared to have sex. My first time was when I was 20, after my sophomore year of college.
However now I understand why they were like that. Kids can't handle pregnancy or STDs alone. They're going to ask someone for help, even if it's not the parent. And if the kid does get pregnant/gets someone pregnant then they add burden that didn't need to be there. I plan on adopting some of my parents lessons for when I have to talk to my own kids about this.
