Anxious about him looking at porn... let me hear some logic please

I am just having a hard time right now and just need some adult support regarding my relationship... I have this overwhelming anxiety of my boyfriend looking at porn before he comes over. Sex is not normal ie sensual and it is getting old and he has admitted to being addicted in the past and I have supplied him with pictures and videos. I want advice from someone that has been through this and has had a successful relationship getting over this hurtle..... if possible. It is also getting to my ego straight up because I am post partum and post hernia surgery and no where near looking like I used to a year ago....
