Bf disrespectful AF

So I've been really pissed at my bf because when he picks something to watch on netflix it always has to do with a slutty girl or sex and I will usually be the "cool" girlfriend and not say a word about it but today he chose to watch a documentary about prostitutes and within the first 2 minutes it showed a sex scene and naked women and I took the remote and turned it and tried to remain calm but my blood was just boiling. To me, that is just extremely disrespectful. And the worst part is I can just predict that he's going to choose to watch something like that. So when it happened I snapped. He said I was overreacting and it's just soft porn and he didn't apologize or anything and made a snarky ass comment "do you not like porn because somebody leaked a video of you online?" Which has never happened he just had to say something douchy. How would you girls feel if your bf did this? Really need some opinions and advice because right now I could just break up with him for his disrespect and the fact that he wants to watch women all the time.
