I think he was referring to his perineum, not urethra. From what I have learned a "harder" seat and cutouts tend to help with pressure on the perineum that can lead to pain, numbness, ED, etc....

I was getting numbness on longer rides, not fun, sort of scary, especially after reading too much on the internet about it. In the process of finding a better solution. Have a Brooks Imperial arriving today, but not sure if that will alleviate the issue - hoping it does.
