Wife’s secret left me confused

So a month ago I used my wife’s phone to search something on reddit (my phone was dead) her search history led me to her view history and it was very rough porn and all the videos she viewed were girls being tag teamed. The thing is we have a dead bedroom and I have tried everything to restart the “fire” opening up about my interests in order to encourage her to do the same but it’s been a firm stance vanilla only interests I’m baffled and I have no idea what to do anymore does anyone have thoughts on how to approach this discussion?
