I haven't been personally affected but I wanted give my 2 cents -hope that's okay. I quoted this part of your post because I think his reaction is very important. He didn't try to hide it at all and even smiled - this is good news really. I suspect he probably uses it occasionally. If this was more sinister in nature, his reaction would have been to immediately shut it off, he would be flustered, possibly angry and upset. Instead your husband was calm, even smiled.

I'm not sure what your views on pornography are. In a perfect world I wish it didn't exist but unfortunately with the internet, it makes it too easily accessible. I think it's possible for people or men to use it moderately, where it doesn't interfere with their relationship. If a person becomes addicted and starts to ignore their partner - this would be a problem.

Do you think you could ccept this if it was an occasional thing? It's a fact that partners masturbate even when they have a good sex life - sometimes it's easier to do it watching porn. The best way to approach this is from a calm stand point. I'm not advocating porn, but just trying to be realistic so you don't think your marriage is unstable. I sense you don't need to worry though.
