I was so immersed in the study that I didn't realize my bladder was on the verge of exploding.
From minute 00:15 to 01:05 you can hear a single first stream of pee
Then from 01:05 to 2:26 I keep pushing because I feel that my bladder is not completely empty, in fact I keep peeing with every push! Pee keeps leaking out of my urethra after every push and groan!
I practically peed almost continuously for over two minutes.. in the end I am exhausted!
