Boyfriend watching alot of porn

about 2 months ago I asked him to not watch porn because it makes me self conscious and alot of bad feelings so he agreed and has told me a few times that he doesnt even if I dont ask. I used his phone today and as soon as I typed www. a whole lost of porn sites and cam girls came up. I havent said anything yet and we're both off at work right now. what should i say to him ?? I'm upset bc he has been lying about that to me even when he knew it made me upset. it's also the fact that its cam girls because you talk to them and stuff like ugh. help me someone
