Boyfriend lying?

My boyfriend has repeatedly told me he does not watch porn, but yesterday when i was on his phone, the first suggestion was xvideos, which is very obviously porn. I have told him in the past that I don't care if he watches because it's just a normal thing but he's always told me that he doesn't need it because he has me. I know he's just trying to be nice and everything but I don't understand why he lied to me. I am so hurt and I feel like I'm not good enough since he said he didn't need it because he has me but now he watches it. I don't know if I should confront him about it since it really wasn't for me to see or what. I'm just so upset that he lied about something he knows I don't care if he does. I don't know what to do. :(
