How to fight urges?

I have a question for you. Surely you have times when pornographic material you have seen weeks even years ago come to mind. also maybe you watch that tv show and you remember the nude videos or pics you saw about one actress there and want to see thay shit again. or suddenly you read the knews and you hear about a new kardashian nude photoshoot that people talk about and you are curious.

How do you fight this urges in your opinion? Either from memories, from connections to things or even news or triggers?
