Catheters can mess with your bladder and a side affect can be incontinence.
They can also cause other infection of your bladder so only get a catheter inserted if you really need it.
I would advise against having a catheter inserted as they are not healthy at all and can do more damage to your bladder.
Nothing was meant to be inserted through your penis so I would not have one inserted into mine.
That is just my opinion though.
