What I had was that friend, and one day he brought that "interesting" photo book with him in school. That was the first and only ever porn/sex thing that happened to me during that time.
Not that I didn't try to repeat that experience. Today's kids seem not able to imagine what it was before that thing called "internet"...
When I was in Grade 7 at a private religious K-8 elementary school, I had a sleepover at a friend's place. The family had four boys and a girl. The girl and three of the boys went to my school. The boys were in Grades 8, 6, and 4/5, and the girl was in Grade 3. The oldest boy was in high school, but I don't know how old he was. Old enough to acquire porn, apparently, because someone swiped a magazine from his room, and the three younger boys and I gathered around and went through it. I knew it was a terrible sin, but I didn't want to be teased for not wanting to see it, and I was curious.
The next morning, the parents somehow found out and had to pray for us before they could drive us to a "March for Jesus", which was the reason why I had spent the night. I felt really bad.
And that's what life was like before the internet, kids! I used that experience for one of Anon's confessions to Eve in my mod. I don't know if younger players can relate to the idea of needing to jerk off with a friend in front of a magazine because you couldn't just take your phone to your bedroom to look at porn, but I figured that, even now, there are parents who have enough control over their kids' internet access that it's not ridiculous that Anon needed to look at naked ladies printed on dead trees.
