I was on my gf’s phone and I found multiple sex tapes with her ex

Me and my girlfriend have been in a loving relationship for a few years now. We’re living together, we share a life, we share everything, she is the love of my life. We are very open with our phones and we’ve never had issues with each other looking through them.

So the other day I was on her phone and we were making drinks and she has this note on her phone with all these recipes she’s made. So I picked up her phone trying to find this note, it’s an iPhone so I swipe down to do the search thing and was typing in “cocktail recipes”, I had just typed in “cock” so far and a message from her ex popped up as a suggestion and I don’t remember exactly what it said but it was incredibly suggestive. We were with her family and I trust her implicitly so I was never going to start a fight then. But that night when she fell asleep I couldn’t help but grab her phone (again, we’re both very ok with this) and look it up.

I scroll to the message and lo and behold I find a series of incredibly intense sex tapes that she had filmed with her ex. It was from before we were dating, so it’s not like she cheated or anything, but the videos were pretty raw. Stuff she has never let me do and has told me she had never done. He was absolutely owning her in the videos, which is a point that her and I don’t get to often, if ever. I will never be able to get those videos out of my head.

I don’t know how to feel about this and I could really use some advice. Obviously she did nothing wrong with her ex but still damn. I’m conflicted, a little aroused, very confused about why I feel that way, and all-in-all just not sure how to feel. Could really use the help!
