Boyfriend watched porn while we were having sex and I didn’t know...

Recently me and my boyfriend had sex one night he woke me up and we got to doing what we normally do, as we started having sex, I notice it didn’t feel like I had his undivided attention, it felt like his mind was elsewhere, i felt it the whole time. So as he finishes I notice he tries to kind of throw his phone to the side so once he fell asleep I decided to go through his search history in his phone because I was aware before that he watches porn but in that moment when we were having sex it totally felt like he was watching something. So I pull up safari and he was watching x videos while fucking me and I didn’t know. We had a discussion not too long ago about us not having sex as much because we weren’t and I told him. He just said he didn’t feel like having sex and he doesn’t want that right now, but he watches porn. I obviously have a high sex drive so it’s never a time where I don’t want to have sex with him. Also when I went through his search history I found that he watched porn one weekend we were together and I’m still trying to figure out when did he watch it because we were together that whole weekend. Maybe when I was sleeping? I just want to know is any of this really a big deal or am I overreacting? I don’t want to bring up porn because it’s such a sensitive topic but I’m starting to feel less attractive. I always wish we could have more sex, do more things in the bed, do different things you know ..? It’s always like we’re doing the same positions over and over . It’s not boring but it could definitely be better. I appreciate any honest and open thoughts.
