pee?

My chinchilla (male) peed on me.This was a few days ago but I have not had the time to post a new question.I did not scare him or anything, I was just sitting down, it was playtime, and he was jumping and running around as usual and sitting on me.So he was sitting on me and he peed on me like while sitting not standing and I wanted to know if I should be worried. Is it normal, nothing or is it a sign of stress? Lately sometimes(not all the time) he had been peeing in his dust bath, I read somewhere that chin's sometimes do that but for 3 days straight he kept peeing on it
