John, despite being shorter, was the "big spoon" as they cuddled, the one behind, wrapping his arms around the one in front of him- in this case, Sherlock.

Because of this, Sherlock could feel John pressing against his hip, but he knew that it was more of the mans need to use the loo than anything else.

"While I agree that this is quite nice, John, I would prefer it if you didn't urinate in my bed because you didn't want to move." He tried to make his voice sound sleepy, but to him at least, it was obvious. To others, he knew, not so much.
