While wikipediaing for one of my classes (We’re reading Freud), I came across this lovely snippet on the Wilhelm Fliess page:
The nose is now known to contain erectile tissue, and this may also become engorged during sexual arousal as a side-effect of the signals fired off by the autonomic nervous system to trigger changes in the genitals of both men and women. A condition exists known as honeymoon rhinitis, in which men and women experience nasal stuffiness during sex, and a small number of people are known to sneeze, sometimes uncontrollably, when engaging in or even thinking about sexual activity.
I can’t decide if this is tragic or absolutely hilarious.
