you have a rare, masturbation
caused syndrome called "Nasal Jizzez" also known as "Nasal Jesus". When you masturbate while sitting and having your penis show upwards, often your sperm will shoot up and hit your nostril
causing a congestion in there during the night. You, like most people, have your eyes closed when you reach the orgasm, so often the "shot" will pass unnoticed.
There is no real cure for "Nasal Jizzez" but to minimize the risk of catching it, you can wear a protective mask. Also, a condom worn over your nose, while you masturbate, helps while, of course, looking a bit silly.
A little trivia for you. This syndrome is often referred to as "Nasal Jesus", because it reminds of other people throughout history who had sperm in a hole of their body without "knowing how that could have happened, Joseph, I swear!"
Anyway, you, dear Vikas, definitely have not been touched by god.
