I don’t see anything you said that it isn’t quite right.
Porn is a distributed form of entertainment.
Porn allows you to get your rocks off. You take views, so to speak and do your thing.
Distributed, in this context, means multiple enjoyers can watch porn on each of their entertainment computers and share the videos, usually to a centralized porn server.
PornHub runs a web-based porn server at pornhub.com so viewers can store their porn in a central location on the internet.
