Husband watching porn?

Ok so my husband is always having to use the restroom for of course #2. Anywho he stays in there for about an hr or so if not less sometimes.

Sometimes he says oh I couldn’t go or I ate to much. Usually he watches YouTube videos of ps4, trailers etc. I just get the feeling he watches porn and maybe silently jerks it or maybe he’s just reading? Idk but this bothers me and makes me feel uncomfortable. What do you ladies think do any of your spouses do this? How do you not let it bother you?
