Husband watches porn and im conflicted

My husband has a right to privacy and watching porn as long as it doesnt lead to physical or emotional cheating and he is a grown man he can watch what ever he wants but i dont like it and i know i cant stop him. How do i live with it now? I just reassure myself and say "every guy watches porn" but it still makes me upset that he does. If i ask him about it he gets angry at me so i dunno how to deal with it myself now..
