Late this coming Saturday...

I'm hoping to do my urethral reroute late Saturday afternoon. I'm going to reroute it below my scrotum and use an 18fr catheter to keep it open...just to see if I like having the reroute before I have my penile urethra closed permanently.

My question is this...will I still be able to use sounds on the penile part of my urethra? I really like seeing how far I can stretch out my opening...
