Boyfriend looking up eating out porn

My boyfriend knows porn makes me insecure but to at least tell me if he's gonna watch it. I found on his search history he looked up "How to eat pussy" and watched some porn videos about oral. He says he doesn't even do oral so I'm what to think... Its not that necessarily porn is a no... I just want to know when he watches it. And if he wants to eat me out why not just ask me to show him what to do.
