Concerns about porn.... Advice nedeed

Believe me seriously wishing I hadn't looked now!!! I'm not going to attack him about it, I'm not that kind of person... I have no problem with him looking at porn at all, it was just a bit of a shock that it was way out there..... We both regularly answer and look at each other's phones.... Still unsure why I did the history search, possibly intuition or something, who knows eh!
