That's true. You'll be a professional nurse in no time. He may not want to even look at the tube poking out for a few days - I sure didn't - so that's your department for a little while. I showered myself once I was up to it, but I didn't have the strength or flexibility to dry myself. And she largely took care of emptying the catheter for me cause I wasn't that stable on my feet.
So you'll be looking at that area in a whole new light. Try to keep your nurse's hat on while you empty the catheter or dry around it, so it doesn't put you off later.
