What would your reaction be if you catch your bf watching porn?

Yesterday afternoon I was taking a nap. When I woke up my bf was in the shower and I hear something unusually. So I decided to listen and see what he was going on. He was watching porn. This really bothered me. I feel like he disrespected me in our own home. Is this something I should be bothered about or am I being extra?

I have nothing against watching porn but I feel like there was no need for him to watch it alone in the bathroom.
