Porn has ruined a normal sex life

So one of the reasons my recent relationship ended was because the guy I was seeing has over exposed himself to porn and can’t get aroused by ordinary, real sex anymore. Is this problem becoming more and more common? It’s really sad as he doesn’t know the meaning of intimate sex with someone you love rather sees sex as a lustful act like ok porn. Who can relate, has been through this or has suggestions for getting past this?
