Your approach does not sound unreasonable. He probably hides it because he feels ashamed of looking at it. That probably stems from the general attitude society has about it, and/or the way his mother reacted when she discovered his stash as a teenager. Also the fact he had prior issues which you don't elaborate on - if he knows he should stop but doesn't, that would do it.
Has he read any of Patrick Carnes books?
That said, are you sure he's just looking at porn and not going farther?
I would sit him down and have a heart to heart with him, and tell him you don't have a problem with the porn but the fact he hides it and lies makes you uncomfortable, so from now on he has to quit with the hiding and lying and deleting browser history. You could also suggest that a keylogger be put on his phone to keep him accountable.
My husband has huge issues with online porn (you can read my story in my sig) and he can't look at it online at all, ever. Mags and DVD's are ok, although right now he's stopped that too because of an issue we had.
