I asked my boyfriend about porn, and now I'm upset.

So as a girl I watch porn. I don't think porn is "bad", and my boyfriend knows about it, and he does too. But I decided to ask about him about it. He told me he uses twitter. And that he looks up a word like "tits" "ass" "c*mshot" and then he does it to that. Am I crazy for being upset? Because I go and I watch videos of two people having sex and that gets me off. I don't look at pictures or short clips where I imagine doing something to those people. I just don't know how to deal with it.
