well, i'm gonna flip back to my earlier stance here.

i assure you that there are nights, after my listless browsings and the rabbit holes i eventually follow, that if my husband saw where i'd ended up he'd either want to yell at me, commit me, and/or divorce me in outrage and horror. and the inverse is true as well, guaranteed.

if he doesn't normally go there and this was just a thing you saw recently in his history, i would urge you to calm down a bit. i mean, because honestly, sometimes you just idly follow links (if creepshots have been his kink before now, i can easily see how he'd wander into 4chan), something interests you, you hang out there awhile, and by the next morning you don't even remember it. the browser history will tell the tale, of course, but not necessarily a complete one.

if your boyfriend has shown no indication otherwise that he's anything but a good guy who treats you and kids and dogs and his parents and his friends well, i really would urge you not to be upset by this particular incident. god help us if we were all judged by our browser history - seriously.
