Finally, something that isn't apocalyptically depressing to write about.
I have been testing this theory for a number of years. I know it works.
It just won an IgNobel prize for Medicine.
Nasal breathing improved significantly after sexual intercourse with climax to the same degree as after application of nasal decongestant for up to 60 minutes.
It also works backwards, if you clean and lubricate your mouth and sinuses, sex improves. Seriously.
(on a tangent- I'm guessing this could be a trigger for hominins evolving hidden ovulation and constant sexual availability. Bipedalism has messed up our upper respiratory system.)
Anyhow- the behavioral consequences of ignoring this phenomenon are endless. Entire medico-psycho-pharma-prison industries are built on nasal and sexual dysfunction.
And yet is is ridiculed.
This may be only thing Freud got right.
