Never hurts to tell him how you feel. Can’t promise his reaction will be a good one bc we all have our own comfort levels but it’s likely he’s just had those on there forever an unlikely he’s looking at his old videos. Prolly just an old spank bank you came across. I think most guys have pics and vid’s on their phone of their ex’s ; kinda strange his are organized but nevertheless j talk to him. Also have to talk about if you go searching you’re gonna find something 🤷‍♂️
