The analogous condition that affects bowel movement is called parcopresis or shy bowel. The adrenaline rush that produces the involuntary nervous system response probably has peripheral and central nervous system involvement. The internal urethral sphincter smooth muscle tissue or the external urethral sphincter striated musclelevator ani especially the pubococcygeus muscle area, or some combination of the above, may be involved. It is possible that there is an inhibition of the detrusor command through a reflex pathway as well.

Point being, while pursuing the comfort of emptying your bladder, you don't want to inadvertently make someone else feel uncomfortable or awkward!
