Boyfriend Problems

So.. my boyfriend and I live together but every couple of days while I’m at work and not at home he gets himself off by watching porn. Idk why it bothers me so much but it does. And we have sex everyday (no exaggeration) and so he always finishes daily but yet he still feels the need to get off. And he says it’s nothing personal but I feel like it is because I don’t like he watches porn to do it, it makes me feel like I’m not attractive enough or good enough. Can someone help or give me words of advise if you’ve ever gone through something like this.. please!
