Horrible at sex

So, I'm dating a guy who is great, but is horrible at sex. He says he can't cum unless he's doing doggy and does absolutely none of the work. It's truly abysmal. 😳 How do I get past the horrible sex? Also, when he tries to eat me out, he just locks up and down. It is not pleasurable at all. Yet, he talks as if other girls have seen his eating out skills as godly. I don't know what to do. 🙈🙊
