I think there's something wrong both ways here. For you, I think you're being a little too exaggerated about what's going on. It could be only here in my place where pictures of naked girls "add up" to your manliness in the eyes of your peers but this could be the case for him. Also, guys during puberty are very *bleep* so they'd need their dose of the stuff often enough.

Now as for his mistake, he's in the greater fault here for being insensitive in my opinion. He's in a relationship and he has those kind of material in his phone without thinking about what you'll think about it. Though you two may have not talked about such a thing before I still think he should have bothered to get your thoughts about it.

I suggest you two talk about it in a calm manner without any argument of any sort as this is a minor misunderstanding. Now if he refuses to remove those photos and/or videos, you are now left with the decision on whether or not you would break up with him.
