Good luck Joliver.....you'll do fine. I'm just down the road from you around the Marion area. I'm five days out now and doing pretty well. You'll be up walking before you know it! See you on the other side brother...
Here's a link to what I consider the best post-surgery suggestions, tips, hints, and things to make it go right.
Hope there's some good ideas there. Regarding the catheter and the penis, use Neosporin or similar around the tube to keep it lubed and fight germs. You will find that you can pull the penis back down the hose somewhat, then put the antibiotic salve on the tube. When the penis is back in position, the inside is also lubed, giving much more comfort. Anothr idea is to really tape or affix the tube to the shaved thigh, maybe in a loop, to keep the tugs and pulls of normal movement from irritating it.
...I have to agree with James, Neosporin or similar....I still have mine in, I just slather that stuff on and all around and I'm off and running! Dont' worry it'll keep up with ya'! As far as your shower though, wow, the day I got home that was the first thing I did, and I do believe it was the best shower ever....I didn't change soaps or shampoos and all is well....enjoy those showers like you always did......Good luck!
