First off I would just like to say that this thread is completely serious, this isn't a piss take (pun intended)
I'm sure a lot of you have had the problem of having a serious urge to pee while rolling but when you get to the toilet you just stand and stare into the bowl unable to squeeze one out. I find it quite uncomfortable and annoying myself and I would like to share my experiance of how I squeeze one out. Also works for other urine retending drugs such as tramadol.
I have no idea and can't remember how I managed to figure this out so don't ask. This works for me, I don't know if it will work for you but its worth a shot.
The 1 thing you need to do this is a cup, glass or anything filled with warm (not hot, to the point where it wouldn't burn on touch).
Well anyways what I do is - get to the bathroom with my container of warm water, drop my pants, pull my foreskin back (uncircumsized) and stick my penis in it... After less than 15 (normally 5) seconds you will start to fell the pee moving through you, yóu get to the point where you are just about to release, then take your dick out and pee as normal.
I was at a festival yesterday in n ireland and was holding it in for 3+hours so I actually went as far as buying a cup of tea, watering it down to a bearable temperature and bringing it to the toilets with me to use as my hot water... It was amazing, because I was extremely uncomfortable until I got it out. It helped me enjoy the festival a lot more
Again this is 100% serious, I'm not messing about, I don't know how a woman would do this for obivious reasons... Lol, but it really helps.
I hope this works for you and if it does I'm glad to help
Stay safe and be sure not to burn your dick

EDIT - only put the top of your penis into the cup (your bellend), no idea why or how this works but it does.
