Hey guys! Glad to know that I am not alone with this issue. Holy sh*t, sometimes it feels like someone stuffed a lit cigarette into my penis hole, and I wanna die lol. The semifull bladder I noticed too, like many other is a precursor to trouble after shooting the load off. This first happened in my teens too, and I was thinking something is wrong. I never talked to my dad about it, nor my doctor since it is an embarrassing problem. I am now 30, and it's happening as I speak :-(

My name I came up for with this condition is "Tippy Burn" lmao. I know that sounds corny, but it pretty much describes it to a T. I start feeling a strong urge to piss right after orgasm, and the pain starts on the lower end of my bladder. I usually take my jug of water and a couple of hefty Tylenols with me to the bathroom. When I start to piss, it actually feels better, and then when that last drop comes out, the fireball at the tip ignites! 

Longest I ever sat on the toilet was 48 minutes. That's the biggest pain in the ass is not knowing exactly how long you're in for O_o. Usually downing a big jug of water, and popping 800 mg of Tylenol or Ibuprofen helps and cuts it down to about 20-25 minutes. This has been the best technique I have found so far....the others mentioned on here I might try too myself. Another possibility I might try...is using orajel on my piss hole since it's a topical anesthetic...see how that works lol. 

I am very surprised that doctors and especially urologists do not have an exact answer on this, since they know the exact physiology of our manhood jewels. But yeah...I'm not the only one and what a relief that is!
