Frequent masturbation????

Okay ladies so serious question...

I'm in a committed relationship and my boyfriend and I live together. He works night shift, and I work days but there a 4-5 hour window we see each other every evening because he wakes up when I get off work and we hang until he has to go back in.

WELL, me being the nosey person that I am, I like to look on his phone every now and then out of boredom. I've noticed he never clears his browser history and Pornhub is his most frequently visited site 😐. And when I investigate further it shows he's on there like everyday... I've even walked in on him rubbing one out before, watching porn.

I've watched porn with him once before we had sex because I thought he was into it... idk we have sex basically every single day too. Is it weird that I'm starting to feel a little insecure and weirded out that he still jerks off to porn every day even though we have ded everyday?!? Help!!
