I grew up with internet porn, but it was also during the transition so I had magazines as a minor also. It was just as easy to have some, the only difference now is the volume that's easy to access. If people had physical porn, it had to be physically hidden, and could then be physically found. And if you're always buying more, it gets harder and harder to both hide it and keep track of what you have so that you'll notice some missing.

Though my first memories of porn are from going to a corner store style store in a mall and just looking through the porn magazines they had on display. A lot of the employees running the stores didn't give a shit. Maybe they wouldn't have sold them to me, but they either didn't even notice or just didn't say anything when I was looking at porn before I even knew about jerking off.
