Busy day definitely is a factor. Every step you take causes the catheter to move up and down your urethra. Considering how sensitive your penis is normally, I’d imagine that sensitivity is heightened during this time. On the second to last day with my the catheter I got a little too confident and ran some errands, I was in so much pain the next morning, I knew it was from how active I was the prior day.
2 more weeks of recovery is nothing compared to the lifetime of relief you are going to feel. You’re almost there man! Enjoy the bedrest, a part of me misses it hah.
