When your woman complains that she doesn't want to have sex because she has a cold and a stopped up nose. When she falls asleep, you put 4 sprays of Afrin on your penis and then shove it up her nose. It will scare the snot out of her, literally. The Afrin will also numb your penis, allowing you to finish in the other nostril.
Johnny wanted to help his woman get a clear nose. So he promptly performed the afrin maneuver.
