no bashing please

my husband and I are rather open about everything but today I unlocked his phone to text someone back for him. his web browser was open on a consenual non-consenual porn video.

if any of you don't know what that is, it's rape play. as a victim of sexual assault myself, it upset me quite a bit. I pretended not to see it.

he's told me all of his fetishes so I didn't expect this. I don't care for him watching porn, it doesn't bother me but this time it truly shook me. what do I do?
