User post: Is porn bad for a relationship?

Ok my fiance and I have been together for over a year now. Six months ago my computer broke and I was forced to use his. I found out that he looks at porn a lot, I checked the log and realized that many times he looked at it right after we have sex, I know he orgasms unlike women it's rather obvious. I confronted him about it and told him that it hurt me that he isn't satisfied with me or at least that is what it feels like and he said he was sorry and that he promised to not do that anymore but then a week later I found more stuff on his computer and he looked like he was trying to hide it from me! Now I understand that men like to look but he promised because he knew it hurt me and now I feel like I can't trust him. He was my first and I want to know am I overreacting? I asked him if he wasn't satisfied with me and I told him that I am willing to try ANYTHING! I just feel like this has ruined the trust I had in him because he lied. I don't think I would feel like this if it had only happened once, I am even intrigued by some people suggesting watching porn together but I still feel betrayed by him. Am I overreacting?
