Serious relationship and porn????!?

[Ray]

I caught a pornstar name on my bf twitter and he denied know who that was freaked out on me. I know its normal for guys to watch porn but for two years he has be completely serious about not watching porn. he thought its not necessary. well I found out he knows exactly who this person is. im afraid to confront him about because its not like he had sex with he just...gets off to her porn. im having trouble. idk if this is normal for him to lie about it. hes never lied to me before. idk if im hurt that he lied or that hes getting off to other girls or both. its not like he cheated but in away I feel kinda betrayed I guess. idk how to confront him about it. hes going to think I went threw his things. I didn't do anything but just look at the public part of his account where I found this stuff. when I seen the porn I just glanced at this phone not even thinking anything of it cuz he was right next to me using it. and he totally denied the fact that he knew what I seen. is this normal? should I be concerned? I feel like im not giving him his privacy and im being a bad girlfriend.
he doesn't actually know her, I just meant he knows what I was talking about and literally said "ive never seen or heard that name before" but its all over is account. I think its the fact that he has always said he hates porn and I find this while hes sitting next to me. so I asked him and he completely lied. I mean it bothers me that he watches porn just a little. it bothers me more that he lied about it and now I don't know how to confront him about lying because hes going to make it sound like its my fault and that theres something wrong with me.
