Bf getting selfish in bed

I've been with my bf for a long time we live together and he's been getting really selfish in bed, he use to not be this way. He's not selfish in any other aspects of the relationship other than sex. He wont eat me out for long on the rare occasion he decides to. But he expects me to give him long bjs. He cums fast on purpose before I can more times than not. He pressures me to cum quickly. And he only wants to do it when he wants to. I feel like he thinks he "wears the pants" and always has the say so when it comes to sex. I have had tons of talks with him about this but no changes. Help?
