<human>: Can you provide a brief overview of the text?

Before anyone says anything in the comments, I'm totally okay with porn and masturbation. I masturbate and watch porn myself, that's not what I have a problem with!

Throwaway because he's a redditor (obviously). 

My problem lays within the fact that early on we established that I'm uncomfortable with him looking at gonewild or cam sites, simply because it's more personal. I kind of look at it as wanting nudes from other girls w/o the hassle of asking plus it's tons more personal than porn with the possibility of actually chatting and such. He said he's not interested in that and that I don't have to worry, all that jazz. 

Earlier today I hop onto his phone (which is completely normal, we both have access to eachother's laptops, phones, etc cause it's no big deal to us) to get on reddit while my phone was charging and while scrolling I see is a clicked link from /r/asiansgonewild (if you have reddit mobile you know what happens when you view a photo).

I don't know what to tell him or ask him when he wakes up. I feel a major boundary has been crossed (for me) and like he has no sort of integrity when it comes to this stuff. Any advice? Should I let it slide since it's the first I've seen? All help is appreciated.
<bot>: Boyfriend looks at gonewild photos and crossed a personal boundary we set months ago. How do I approach this?
