Snakes pee, especially if they have recently had a bath, have eaten, are relatively comfortable, and last but not least, have been moving around a lot. Just like with any animal, movement stimulates your bodily functions, so after an hour of being out and active, pee is not surprising. I have a retic that pees after 15 minutes of handling like clockwork.
"defensive" pee is when you pick them up and they spray everywhere, but that is really the fight or flight mechanism.
Musk, that is what a snake does to you to make you put them down, and boy does it work well. Ball Pythons are not known for their musk, so don't be worried about that. Just be weary around very large male anacondas, they can really drop a doozie on you, and it tkaes forever to get out.
