Is it odd for a guy to do this?

So, random question: my boyfriend will randomly smell me. Not in a creepy way (usually xD), but if we're snuggling he'll take a whiff of my hair or he'll nuzzle my neck and smell. I find it a little odd, but then again I also sleep in his hoodie. (It makes me feel safe, which is a little silly, but I don't mind).
