They sometimes insert it, in surgery.....and if not, you can request it be placed in surgery....that way your asleep. When you wake with it in place, you will sometimes feel pressure, like you need to urinate, even though your bladder will be emptying into a drainage system (Bag). A small amount of sterile water 5-10 ml., will be inserted in a port, which will fill a small balloon inside your bladder, after it is checked for placement....this will keep it from falling/pulling out. Be sure they tape it to your thigh, so when you move or get out of bed, it doesn't pull... that can be uncomfortable. When the Doctor orders it removed, they will remove the sterile water from the port, they inserted it in, thus deflating the balloon, it then slides out easily... with only a slight burning feeling at times....some men feel nothing.
Honestly, the thing most men have problems with is, before they start to clean the meatus off, they must hold "your member" , then they pull it upward and slightly backward to straighten the urethra, as males have two curves in their urethra. Alot of men seem to be embarrassed by this procedure. Don't be...just breath slowly and relax. It is a very quick procedure. ( unless you have scaring, stricture and/or narrowing of the urethra or Phimosis, which is : constriction of the prepuce (foreskin) ...but don't worry...you won't have either of these) They always lubricate on about 8 inches of the cath, but anesthetic gel can be introduced into the urethra too.. They need it for accurate measurement of intake and output.
Best of luck........you will do just fine
