Hello and welcome to HCM
I am afraid bed wetting
is not normal at the age of 33.
The features that you you have mentioned- unable to control urination at odd places point towards a condition called DETRUSSOR INSTABILITY.
This is a condition where the muscles of the bladder are unable to contrat and relax normally, there is some kind of instability in the muscle.
The normal phenomenon of controlling urination at odd places such as in public is due to voluntary contraction of these muscles.
I suggest you to get bladder studies done by a specialist which will exactly find out the cause of this problem.
After knowing the exact cause you can get appropriate treatment.
Thanks and take care
