What to do...

Found porn on my fiancé phone... Honestly I thought he stop watching it when he moved in with me but it hasn't.... I give him sex ALL the time I don't know what to think of this... I am kind of done finding it in plain sight without him just talking to me about it. And yes I trust him 100% but I needed to search something up on his phone and it was the first page on the browser .. :/ I need advice guys...
