I was telling this story to my friend last night and she encouraged me to share it with the redditors of TIFU. So here we go.

This happened a few months ago. I live with my father and he was out of town due to office work for some days. I had the house all to myself during the night. (You know what this mean.)

I'm a person who enjoys consuming media in lavish ways. Screw watching movies on your mobile. If I'm looking forward to watching something, I would get the highest quality print and play it in our living room TV. The room has some nice lighting which adds to the cinematic experience. For obvious reasons, I cannot do this with porn. But this night was different. I had the whole house to myself. It was middle of the night. I was not expecting any phone calls. There was no chance of getting interrupted while I would do the deed. And so I decided to make the most of my session.

I hooked up laptop to the TV with the HDMI cable, dimmed the room lights and turned on the showcase lights on the TV cabinet. The setup looked beautiful. I got a box of tissues and settled myself on the couch. I decrypted my "homework" folder and played one of my favorite assignments. All is going great.

Now, I'm a person who likes to self-explore. There is much more to masturbation than just having an up & down motion along the shaft. If you're willing to explore and be bold, you can enhance your experience so much, my friends. The video I was enjoying had some light gagging. And I wanted a bit more stimulation. But I had the brains to be aware that I cannot simply just put my fingers in mouth which has been all over my dick. Ew. So I decide to cleanse it. Should I have gone and just wash my hands with water and soap, yes. But no, I went to my bedroom and got a little bottle of alcohol based hand sanitizer. I pour it over my hands. Great, they feel very clean now. But I realize that I would touch my dick again. And that would get my hands dirty again. Mind you, it wasn't like my dick was filthy. I had not showered that day so there was mental barrier of hygiene. So I had this bright idea. Why don't I clean my dick with the sanitizer. It's a very dense liquid but "hey still liquid, so it should also act as bit of lube right" I thought.

I pour the sanitizer over my dick. Since I was already hard, it was easy to pour it over the head. Gravity helped me out in spreading it over. I don't remember if it was me or gravity, but somehow a little bit of the alcohol based sanitizer slipped inside my urethra. There was no immediate reaction. I closed the lid of the sanitizer bottle and got hold of my very clean dick with my very clean hands. And then it started. I felt a tingle inside which disturbed my up & down motion. So I slowed it down. I was so aloof of the fact that the sanitizer could be an issue. After slowing it down the tingle subsided for a moment. I was relieved. And then it came back with a vengeance. It started again with a tingle. I slowed down again. It escalated to mild discomfort. I started thinking what the hell is happening. It increased to a subtle burning sensation. I turned to look at the sanitizer bottle beside me and started putting the pieces together. But it was too late. I stood up suddenly because now the burning sensation was enough to cue my instincts that whatever went inside my dick needs to be washed out. I rushed into the washroom and ran a lot of water over my dick. The pain and burning reduced but the insides of my urethra were still in discomfort. I decided to point the jet spray directly at my dick from the top. The pressurized water spray could cause more problems but luckily it did not. It helped my get some sanitizer out and dilute the remaining. After some 15 minutes of constant washing, I was back to tingling only mode. I dried myself and went back to complete my session because why not.

​

TL;DR I wanted to have a clean dick while masturbating so I poured some sanitizer over it. Ended up running water over my dick for 15 minutes to reduce the burning.
