Doesn’t want sex but watches porn

Sorry for the long post, I’m just looking for a bit of advice on what to do. History: I’ve always had a higher sex drive than my partner, there have been a couple of times this has caused a slight niggle but nothing major. During pregnancy he said that he didn’t feel comfortable us having sex while I was pregnant, I found this odd but I didn’t really fancy it very often - thank you very much daily “morning” sickness - so it wasn’t too much of an issue. He said that he knew this would change afterwards so I wasn’t too worried. We’re now 7m pp and have only had sex once at Christmas, he shows no interest in me physically and whenever I’ve discussed this he says it’s because I’m still EBF so he feels like my body is still our daughters and it wouldn’t be right. I had my suspicions so I’ve looked at his computer this morning and can see that he has been on a lot of porn yesterday while I was out with baby all day. I’ve then looked back and can see that basically whenever I’m out he’s looking at stuff online. I’m okay ish with porn but only as long as we’re having sex as well; I have expressed a number of times previously that I find it really hurtful that he would rather look at porn than have sex with me, it really effects my confidence and I don’t think it’s right. My dilemma now is, should I bring the subject up with him, and how? Obviously I shouldn’t really have looked at his history (we do share the computer for Amazon prime etc so he knows I go on there frequently) but I’m now really hurt and I really don’t understand why he’d rather look at that then actually have sex. Yes my body has changed but surely actually having sex is better than porn? I’ve made it abundantly clear that I still want him but I get nothing back and it’s really getting me down and making me feel self conscious etc.
