opinions please!

I need Opinions.. Awhile ago I caught my husbands looking at porn  (movies) so he actually got rid of them cause he knew I was bothered by it. Now I find him going through it on his phone.. Obviously he doesn't know I went through his phone but I did. He never has strange girl text messages or even porn pictures saved on his phone for that matter and he's always been the best husband I could ever imagine But being that I can't confront him I've been kind of having this weighing me down. Sometimes I agree I look at porn too so I can't be hateful about it and I did ask him about watching porn together and then that was the end of that he didn't say no but yet didn't say yes. Does anyone have guys like this? Or a similar situation. I don't know how I should feel. I know I turn him on, and we def don't have any problems with sex with have it all the time that's not the problem but me knowing what I do now it's making me want to "one up" it a little more and pleasure him everyday cause "if I don't" he's gonna go to porn on his phone and then that makes me feel like shit "cause I know he will". and again I turn him on but porn turns him on I feel in a totally different way. How are your feelings ? I've been wanting advice on this topic
