you have boner tissue in your nose

You know how you can only breathe easily through one nostril at a time?  You have boner tissue in your sinuses.

"The nasal venous sinusoids form a spongy tissue, similar to erectile tissue, which is particularly well-developed at the anterior end of the nasal septum and the inferior turbinate."
