bf won't anymore

So my bf and I have been together for over a year. He used to eat me out everytime we decided to fool around and now he doesn't. He just fingers me. I've always been clean and well kept down there and never had complaints... idk it makes me feel like I'm not good enough for him or something. And on top of it I always give him head even when he doesn't ask for it and I feel like it's like pulling teeth when I want to be pleased.. I feel lost he has lost interest or something.. anyone else gone through this or know how to have him go down?
