Brother, It won't be as bad as you imagine. You are going to pee on yourself at some point...I'm being as honest as I can here...After a week with my friend Fred (that is what I called that firehose shoved up my tee tee) and after the nurse takes him from you....Well lets just say I was very happy to walk out of there with a depends on. (I didn't think to bring undies on that glorious day) I mean after all that you go though to get to there you won't be sweating the small stuff...No pun intended. I kept wearing depends at night for a week or so after to save the mattress well...and then pads for a while after that...
Good luck...start kegals today...remember what it feels like to start and stop because you'll depend some on memory to help as you are getting back to normal..
and remember...before you know it you be good as new...AND no more staring at the wall in front of you waiting on the stream, in fact it's quite the opposite...you get used to unzipping as you walk but its' still all good.
Prayers going up...
Hawk
