My husband watches porn

Me and my husband have been together for 6 years and married 3. Our sex life is great (we have sex 4 times a week roughly). However, I work nights and I noticed that whenever I work he watches porn (twice a week that I know of and we share a google account that's how I found out). Ladies is this a normalized thing? How would/do you feel about your significant other if you caught them? 🙁
