I thought my OH had loo issues

So my phone was dead and I wanted to use the internet, my OH was outside having a cigarette so I grabbed his phone and opened up his browser ( we are not possessive over our phones we go on each other’s all the time if we need to ) and a porn page pops up. So I look through his history and literally every signal day he has been watching porn and I scroll back a good few months. We have a little boy who is 8 months old however we are sexually active a fair bit considering. Is this anything to worry over, I’m not really fussed he watches it just more concerned that I’m not ‘meeting his needs’. I haven’t confronted him yet but feel I may have to soon as he disappears off to the loo about four times a day for up to twenty-twenty five minutes at a time and now I no why.
