I found my girls porn. I need advice.

So this past sunday I was using my girlfriends tablet, she let me borrow it to look up a car website. Within the first two letters of typing in the car website’s name a whole bunch of porn popped up and was saved to her favorites. I got curious to go further because it wasn’t just history searches they were actually saved as favorites. So i continued on just to see what kind of porn she was looking into. Turns out a lot of it was gay male porn. Then from there some lesbian porn and she even had some of ther favorite lesbians saved in there. She also had some light bondage and some kinky things of that nature. I’m not overly concerned with the porn I’ve viewed much of the same and prolly a lot more myself.I just don’t know how to approach it. The reason I want to approach it is because it is because #1 it kind of turns me on to know she’s into porn. Especially some of the kinky stuff. We’ve talked about sex before and kinky stuff but she always said she was against it. #2 I think that our relationship could benefit from talking about it. We’d be getting to know eaxh other on a really intimate level. For the longest I’ve never thought that she would be into that kind of stuff I found and it means a lot to me to be able to relate to some of it. What gets me though is that she’s always thrown out this facade that she never masturbated, so this all comes as a (even though surprising) pleasant surprise. So, how would i go about talk with her about it? Now that i know she’s really kind of kinky i want the opportunity to bring that side out of her and connect at a much deeper level. How do i approach this
