I do not think an “addiction” is the problem. Obviously, everyone prefers the real thing to porn.
What has changed is the availability of porn introducing an extremely low cost alternative to sex, reducing the impetus for making the effort to find a partner (relative to previous times). Maybe even reducing the impetus to putting in the effort to seduce an existing partner!
Of course, it is not uniform across all men of course. I suspect those who are able to attract/interact with partners more easily will opt to do that, and those that are not will opt for the easier, lower cost option (even though there may be other long term costs).
