It's not the pornography that's bothering you - it's your boyfriend's response to the fact that it bothers you. The fact that you have caught hin 'a million times' indicates that he makes no effort to take note of your feelings, and access these sites when you are out, or asleep, or doing something else. I would agree that looking at porn per se is not an issue to worry over, but your partner's unwillingness to address your concerns is something you need to talk to him about. He may be embarassed, but tell him, if he'as adult enough to be in a relationship, he's adult enough to discus its issues, and they are not always happy discussions. If he refuses to discuss your thoughts, you need to think seriously about where this relationship is going. Good luck.
