Not another porn question?

what would u do in a situation if a man is watching porn behind ur back and would act really mad if he was to catch u watching it. i mean why do some men watch porn behind women back and act like they dont and instead get mad at women for little things. my husband was so miserable and made me miserable. i mean i think he will always try to watch porn behind my back and act like he didn't even if i told him to come to meif he wants to watch it. why would u think some men do that.
