I don’t know if you are CAtholic; either way, you might pick a parish and speak with the priest there; they may have a booklet or a recommendation of a book on such matters - which is often but not always parallel with pornography.
If the matter is egregious enough, my understanding is that there are groups similar to Alcohol Anonymous which may be helpful.
I don’t know of any social media sources, but Catholic Answers has a number of books and cd’s and things. You could go to their main site and click on shop and then put in “pornography”. Another book that helped me, although not from Catholic authors, is a book called Every Man’s Battle. It’s a really good, starkly honest book.
