The last couple of times that I've used my UT I've actually felt lube getting inside my urethra. It stings a bit but isn't too bad. The canal of the sleeve is just so narrow that some of the lube is pushed inside there. Has anyone else experienced this? And do you think this can be harmful? I always take a piss after a FLight but still... Maybe some bacteria can get inside with the lube. What do you think?
