I was sure hoping for a better outcome with your trip to a urologist.

I am not much of a bike rider, but I wonder if adjusting ot replacing your bike seat would do something. Perhaps one of the big, wide seats? May look goofy, but if you are seated on your rear and not any part of your groin, that can only help. I have seen some new seats with an empty spot in the center just for this reason, since most of your weight should be on you butt bones anyway.
