No sex vs porn

Long story short...my bf has gotten off an opiod addiction. During his withdrawal and getting back to normal period our sex life went from almost daily to maybe once a month, which I completely understood. It's been just over 4 months and he is almost normal. Except our sex life still. Today he asked me to look through his internet search history to find something for him...a crap ton of porn came up. His excuse for not having sex was that he had stomach issues, no energy, no desire...yet he obviously is using porn on a regular basis as opposed to having sex with me. Would you confront him?
