Spooning

So I’m 5’0 and my boyfriend is 5’10 so naturally when we cuddle you would think I would be the little spoon right? but my boyfriend always wants to be the little spoon. I hate it but I do it for him sometimes because I love him 😂 anyways he told me there are two reasons he doesn’t like being the big spoon. 1. Being that he likes being hugged (which I understand) and he wouldn’t tell me the second reason because he said it’s awkward. Any idea what that second reason might be?
