Has anyone been triggered/effected by pornography?

My H was looking at some pornography online and I happened to see it as I went in his office (home office btw). He didn't seem to mind that I was there and smiled when he saw me. I just said oh geez and left the room. I'm feeling really hurt by this and disgusted at the same time. I plan on discussing this with him but I just wanted to see if anyone else has had this experience (who also has a past history of SA).
