Watching porn?

How do you guys feel about you s/o watching porn? I'm not sure how to feel about walking in on my s/o with a random boner in the bathroom because of it. I know it sounds weird and maybe selfish but I just want to know how others feel because of right now I'm kinda mad that that I was around... and then he tried to delete the history omg lol which made it worse! I mean I don't really mind up unless Im around I guess.. anyway tell me your stories ladies!!!
