Husband watching porn

We’ve been together 8 years. 2 young children. We have an agreement we save our pleasure for each other. No porn.

I am not ok with porn period. He knows this an agrees. I am willing and able whenever the mood strikes. We still have sex 1-3x a week.

Well he watches it probably once a week. And he deletes the history on his phone but not his google history so I can still see it.

Well I want to address it but I don’t know how. Last night he was bothered to have sex well it was because he watched porn 2 hours prior.

He knows I check his phone because I’ve caught him before. But now he deletes it so he thinks I don’t know.

I don’t want him to be embarrassed. It’s normal. But I want him to know it hurts my feelings that 1. He’s watching it and 2. He lies to me about it.

Where do I start?
