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."

Sure, it varies through the day.  Cover one nostril with your thumb and test it out.  It's not a sudden switch, so try throughout the day.

what the fuck is a boner/erectile tissue???
