Nothing feels more painful than bearing the pressure of a distended bladder. All the wrong things happen then, the bus ride gets bumpy, people elbow you accidentally, and passing by the lake watching the water takes forever, further aggravating matters. It takes a lot of will power, muscle power, and clenching power.
Nothing feels more blissful than letting go of the distended bladder. It is like piercing a pin through a balloon and watching it deflate slowly. The relief, the ecstasy, the letting go of clenched muscles while listening to your heartbeat- I am convinced that the involuntary moan sounds more authentic than an orgasmic one.
Just my 2 cents on the pangs of distended bladders.
