I used to experiment with it in my late teens. Didn't do it cause it felt good or anything. Around that age I just liked trying shit to seek some kind of sexual thrill to get off on. I decided to put a stop to it one night however. It would be the last time I've ever played with my pee hole.

Be me. 20. I had gotten this idea to shove cum lube down my urethra from watching porn of men doing the same thing with other liquids. I grabbed a kitchen syringe and filled it with about 10ml? I shoved the nozzle down inside and pushed the plunger down gently until I felt resistance. Could feel the lube inside my cock. Stung a bit but not as much as the times I would insert metal objects. The act got me super horny, I pressed forward fueled on the ecstasy. I pressed down harder against the force until I felt it break it's way deeper down. I can still remember the pleasure I felt around my pelvis it was indescribable. Immediately jerked off after removing the syringe and came buckets seconds later. Cum and cum lube mixed together in hand. Possibly the best orgasm of my life. Slight discomfort in lower stomach and deep inside penis after but I just clean up and go to bed.

Next morning get up to pee. Dick looks fine but as soon as I try to take a leak, feel immediate blockage followed by pain. I stand in front of the toilet for about 20 minutes unable to piss. Terrified I'm going to have to go to the hospital for my first sex related injury, decide to suck it up and force myself to piss through the pain. I push against the blockage until I feel something finally break through. Stare down at my peen the whole time before witnessing a straight clear red, piss mixed, stream of blood pour out of me. Extremely painful. Have to cut stream mid piss session just to finish draining my bladder. This would become routine for a week before I started noticing signs of clearer and healthier piss. Experince scared me cared me off of sounding for good. 6/10. Would recommend.
