Found screenshot in boyfriend (27M) phone. I am (28F) not sure what to do.

I found this screenshot in my boyfriends phone of “secrets benefits” and behind it looks like a certain website called Leo***. He accidentally screenshots things all thetime and doesn’t mean to. I asked him about it and he said he wouldn’t go on something like that as that’s is not his intention being in this relationship. He said maybe he accidentally clicked on a link and it brought him to it and he left but he would never go on it and search it up. He is an amazing guy who I trust so much. I got out of a topic 8 year relationship with a liar cheater and manipulative and I have never once got a bad feeling about who I am with now. All his friends and family say he is the most loyal guy and cheating is out of his nature. As well as my friend who got cheated on said she has such a good feeling from him and she’s has only got that from one other person. Basically asking if I should believe him and trust his word as I have such bad trust issues from my past or I should look into it deeper. It does lol a lot like the website behind but again it could be something innocent and it could be from a p*** website by accident. He has been honest with me about everything works through my trust issues with me and we have an open phone policy. He has no issue me going on his phone and I have never once found anything sketchy on it and he’s basically a very chill guy who just wants to be with me live an happy life get married have children and grow old together. What do y my guys think? I want to be with him and trust him and believe him. How do i trust his word and letRmy society leave my body?

TL;DR found this weird screenshot in my boyfriends phone, he is so loyal and trusting so I am finding this odd. Hopefung to trust him and stay with him.
