My sex education class, and yes I really wish I was lying here:
They separated us by gender. A guy in his early 20s maybe late teens came in, hadn’t seen him before. He gave a talk about how if we watched porn we would only be attracted to “a plastic bag” and not love our future wives while one of the super Catholic teachers we had nodded in agreement. Looking back I am pretty confident he was some college student in some religious school.
Not so fun fact, I have a sister who became a mom at age 19.
