Boyfriend watching porn. And trying to hide it.

So my boyfriend and I always watch movies on his xbox at night well when he went to get on Netflix it showed that he recently was on a porn site. I asked him about it and he was like "it's been on there" I'm like but it's a brand new Xbox I just bought it for you. And he's like "why are you upset don't I give you enough sex". Is there something wrong with me? I feel like there has to be if he still watches porn. Please give me some advice. I don't feel like I'm good enough for him now.
