surfing the porns sites

I dont mind when my significant other surfs the porn sites in fact i think it erotic and can stimulate more sex. what i mind is the fact that he gets lost in them and forgets about me. I waite for at least  an hour sometimes just for a video or game that i wanted to play. And we start off as a couple looking for another woman, but end up he just looking for himself.  I even leave to give him some time. But alas  that does not even help  He. blocks every thing out or acts likje he does.   I have a feeling he thinks I m always trying to start problems. I feel like maybe I just dont undertand  porn.
