I've had 5 or 6 cystos as well... I dislike going to the dentist about as much! The first time is always the worst! Not a big deal anymore, except it is uncomfortable peeing and having sex for about 12 hours afterwards
The nurse just squirts in some numbing KY-jelly stuff about 10 minutes before the good ol' plumber's scope goes in!
It would be more exciting if the urology nurse didn't look like Selma from Nightcourt... but I guess thats the point.
