Suggest Remedy To Treat Cut In Penis

Hello, I was committing intercourse with my couch and on the wooden end of my couch, I cut the inside of my penis, in the hole, about a half of an inch from the entrance. It consistently stings (On a scale from 1-10: 1) there, I saw a very little amount of blood a bout 10 mins ago, and now it is gone, and I could never see the cut. I want to know, is there any danger, and can I urinate right now? And most importantly, what should I do?
