Not a highly talked about condition.

I had this later on in life and was worried so talked to my PCP about it. He said it usually is caused by scar tissue and not something to be concerned about unless it affects your ability to enjoy sex or brings you pain.

I had some type of check done (can't remember as so long ago) where they went up my uretha and looked at something. I can remember when I first went to pee tremendous burning pain inside my penis. I was told probably the result of the catheter and scope.

I was told would heal but would have scar tissue there. Nothing until later on in life and some curving. You asked what does it cause. If minor, nothing other than worry. If drastic can affect enjoyment. Just have your urologist or if your PCP is experienced check it or discuss it with them.

Mine never got worse and for me has come the norm for decades now.
