Would you leave him?

If you knew your man wouldn't cheat on you, is very open with passwords, never late from work, always home, sex life active/good etc but you also knew he liked watching porn like if you left for a few hours he may jack off to porn. Would this phase you or would you leave him? Like is this normal for guys to do? Can a man be faithful and in an exclusive relationship and still watch it? He's so good to me....
