Well first off, if the girls father can't trust her to not go off and fuck every guy she meets, then MAYBE he shouldn't be a father in the first place. Yell at your own shitty kid before you mad at someone else's.
Second, most of the people that have responded are twice jokers age, so I don't know how things went down in prior generations but heres my take on it. Virtually all of the kids I knew in highschool that were sexually repressed and had parents like this went of to college with NO prior exposure to situations like this and not only ended up fucking everyone they met at a party after a few drinks, but also ended up fucking themselves over pretty bad as well. On the other hands, my close group of friends, both guys and girls, had parents who didn't mind that kinda stuff. And none of us have had to get tested since we left home.
