My Boyfriend Won’t Eat Me Out

I’m 17 and my bf is 19. We’ve been together almost 2 years. He doesn’t like eating me out and anytime he does I always have to ask. I just find it sexually frustrating because I’m willing to do anything sexually. I give him bjs anytime he wants and it and here I am having to rub my clit during sex otherwise I won’t cum at all. I think my bf finds eating me out gross or something I can sometimes see it on his face and it turns me off. I’m clean! I wash well and I fully shave. I even put lotion on my upper legs so I smell nice. I’ve talked to him about this many times but he always seems to not care about fully satisfying me. Help :(
