The manga and databook said what I said above. They speak about leaning towards one nature that is shown through the chakra paper. I mean, you can lean towards more natures, but there's always one where you lean the most to, and that one is your affinity.

If this was not the case, then as I said, would the chakra paper crumble and get wet? And wouldn't Kakuzu need only four or even less hearts?

Having more than one chakra nature you lean to the most is not possible and wouldn't make sense in the story. You really hate my persnickety approach that much? :(

The manga doesn't say it though (at least not in chp. 315-316), and the normal definition of affinity does not imply that you can only have one. Do you know of any dictionary that describes it as such?

Why can't the paper crumble and get wet? Haven't you seen a crumbled wet paper before? But the thing you said about Kakuzu makes sense, and on that I completely agree that it strongly implies that ninjas are limited to one affinity, but that is ceteris paribus... it is an observed pattern and not a rule, so it is not beyond having exceptions.
