A recent publication by S. Zarrintan, entitled "Ejaculation as a potential treatment of nasal congestion in mature males" has my head and nasal passages spinning. Published in the 2008 Journal of Medical Hypotheses, the article suggests that sinus sufferers simply masturbate as a way to clear nasal congestion.
The author suggests that ejaculation stimulates the adrenergic receptors, causing a side effect of decongestion. With proper masturbatory and sexual intercourse scheduling, you have a clear sinuses for the rest of your life!
If I had only known about this when I wrote that artlce on the benefits of masturbation!
