Age gap relationship, porn over use?

Ok I f30 dating a m54 for 3.5 years. He has been finding it more difficult to finish the last three months. Blamed tiredness, age etc. Found out today he’s watching porn 3-5 times a week. I’m not against porn. I’m also a filthy freak in bed, attractive, and willing. Am I being dramatic asking him to reduce it to get some of the intimacy back in our relationship?
