I think OP meant regular old movies, not porn, like PirateBay.
A few posters are acting like the poor lad's addicted to porn just because he panicked and it's likely not the case.
The messages are designed to make you panic. Like I and a few other posters have said, we had momentary panic when we first encountered the scam and we don't watch porn. The one I had mentioned my "laptop" and film they'd taken of me on my laptop not a phone. It was an earlier version of the scam when smartphones weren't as advanced as they are now and laptops and tablets were more popuar.
I didn't have a laptop, I had a desktop that had no webcam and I had never watched porn on it or even 18 plus movies because it was in the family room but I still have a minute of fear when I read the email because it included personal details like passwords.
I'm sure he does watch some porn like pretty much every other teenager but having a minor panic over a scam email doesn't mean he is an "advanced user" of porn or has a phone full of dick pics and sex abuse images.
