Need advice

My husband and I have been married since October, I've never looked at his phone before but today he left it lying around and so I just wanted to look and anyways I went on his FB activity log and in January he looked up "model girls" anf when you click on it is all pages for sexy girls etc. I'm kind of hurt by it since he knows how self conscious I am and I don't know if I should bring it up or not? I know it was a few months ago but what of he's been looking things up but deleting them?
