Funny that you mention

"Do the sensory neurons stop generating input after a while, or do we just stop noticing the input- and at what lpoint do we stop?"

In animal physiology we learned that if you bend a crawfish's tail you will get a burst of action potential. However when you bend it and hold it you will notice that the rate at which action potentials fire will slowly decrease. These receptors are called tonic receptors. I think it is very likely that our skin have these receptors and so we don't notice senses like our clothe touching us. But the moment we receive a different input, say for instance the tag on the back of our shirt is scratching our neck, then the action potential will fire rapidly again. However, I am unsure when these inputs stop.
