Private stripper party

My boyfriend went to a bachelor party a year ago and the event popped up in his Google photos as a memory. Although I was fully aware of the event and that there would be strippers, I’m pissed at what I saw. There was only ONE stripper, probably from like craigslist, and she didn’t appear be professional at all. There’s tons of videos of this FULLY nude girl dancing on the groom. The men were like playing with her as she’s dancing and my boyfriend is recording it, zooming in on her vagina and stuff.. I guess I’m pissed because I didn’t expect it to be that kind of party since he’s normally reserved about stuff like that. And also it makes me wonder if he touched her too. Had I known it wasn’t gonna be a professional stripper I probably would’ve asked him not to go. And now I’m here a year later, pissed at the whole thing. Am I just overreacting or should I bring this up to him?
