Hi - I hope you are feeling a bit better now. It sounds like a chemical burn, which should heal over time. Just make sure to leave the area alone - don't rub it, or use your hands to examine it, and just wash with gentle soap and water, and pat the area dry instead of rubbing it. If it doesn't keep getting better, you should definitely see a doctor, but it is likely just taking some time for the skin to re-grow, since the urethra is a very sensitive area.
I'm not sure what problem you were trying to fix by putting undiluted alcohol on it, but please don't do that again. There is no medical problem that you can solve by putting harsh chemicals on your penis.
You haven't stated an age so, if you're a minor, you need to go to your dad and tell him - and quite possibly SHOW him - what's happened. If you're an adult, you should have gone to the emergency room as soon as it happened. They've seen stranger things than someone pouring alcohol on their penis - I assure you. If it's healing, and there's been no major harm, and you can manage the pain, keep it as clean as possible. And the only thing you should put on it should be a very thin layer of petroleum jelly.
Good luck!
