Boyfriend watching porn!?

Okay, soo my boyfriend watches porn at first he hid it from me and I told him I didn't really mind that he watched it because all men do...right? Well now he just leaves it on his safari and its kind of irritating how often he does. Now I'm not really sure how I feel about..it kind of makes me feel like I'm not enough for him. We live together so we  have sex everyday.. it's not like he's not getting any.
