ELI5: How can we not feel any of our inner organs? Or better why do we only feel pain and no other feeling with them?

Because you don't really need to.

Actually, you can kinda feel your organs. You can have sensations of pressure or distension in your stomach and bowels. If you take a deep enough breath, you can feel some shifting of your internal organs, or viscera. 

But you're right that, for the most part, proprioception of your internal organs is largely restricted to pain. The reason for that is because the only time you'd ever really need to know anything about your internal organs is when they feel pain. Pain is a sign of something is wrong, usually the first and most urgent and most characteristic. You don't need to know the exact size and position of your stomach at all times of the day like you would with, say, your arm, which you rely on to interact with the outside world. You don't need to know which lobes of your liver are currently working the hardest; that's just taking up space in your conscious mind and it's not information you can really do anything with. Visceral sensation is only valuable when there's something wrong with the actual viscera. Otherwise, if all systems are working fine, why clog the bandwidth?
