@Lookingforhelp86,
Two questions.
1) If you are having sex every night, then how is his use of porn hurting you in any way? It doesn't seem like it should be a problem for you. Why does what he watches in his own time bother you?
2) If it does bother you, and you really can't accept this, then why haven't you dumped him already?
It doesn't really matter whether it is normal or not. You can look on the Kinsey webpage to see what the average man says about how much he uses porn. But who cares, what matters in your relationship is you and him.
Whether you think this is a problem or not is going to change anything. This will only change if you boyfriend thinks it is a problem... and porn is much less harmful of a habit then smoking. Maybe he doesn't feel the need to change. In this case there is no way to force him to change, this isn't your place.
It is always good to talk to your partner about how you feel... of course listening is an important part of communication too. If you can't accept how your boyfriend is, then you should end the relationship. You can't force someone to change. You either accept them or you leave them. That's how it works.
