talk to him. di po kasi kami ang makakasagot nyan. depende po kasi sa usapan nyo yan as a couple and sa values nyo both. some married couples think this is normal, some don't. some people dont mind kung nagpoporn ang asawa nila mapa babae o lalake man. need niyo po pag usapan talaga.
personally, i believe watching porn and mast*rbating is sinful because it displeases God dahil ito ay lust toward another person and not out of love. not everyone believes this, so best is to check with your husband and let him know that you feel hurt.
