I'm mad at him for cuming w/o a condom on.

My BF and I were having sex in the shower, and I usually let him start w/o a condom, get a few strokes in. Well we were doing that then all of a sudden he pulled out. I didn't really think much of it until I went to go get a condom and he stopped me. I was like, what's wrong. He wouldn't tell me. I was like WTF babe, what's wrong. And he said he came. And I said are you serious???

And he went on to be like, oh I pulled out it's fine. I proceed to be more pissed, we just got over a scare the last time this happened. It's not fine, just using the pull out method is not fine with me & he knows this. Yes, I know, I shouldn't let him even near me w/o a condom on, so it is partly my fault but I still have a right to be upset.
