Sorry for the cryptic title, but the true nature of my issue might set off privacy filters...
When I bike for any duration, I develop a dull, aching pain in my left testicle. Standing, rearranging things both help a little, but generally only for a few pedal strokes. I'm tempted to guess it's a twisted testicle but I'm not sure. Anyone have any suggestions?
NOTE: early in the season (or in my training season -- this year *my* season didn't start until a few weeks ago), this pain crops up after 30-40 miles. Later in the season it develops after more mileage--say as high as 100+. I'm somewhat overweight (20 lbs), and I spread fat across my body. I'm inclined to believe it's the rubbing between an overly-large thigh and my, uh, anatomy that might be at play. But I'm totally clutching at straws here.
I had "numbness" problems with most of the bike saddles until my LBS reconmmended I try an ISM saddle (search for "ISM bicycle saddle" in your browser). The ISM saddle looks like a toilet seat. In fact the guy that invented it dreamed up the design while sitting on one. This saddle is great. I have one on my road bike and hybrid. When you first ride with it may feel a little unstable but it only takes a few rides and you are hooked. I would definitely investigate this saddle. I am 67 years old, 6'2", and weigh around 230 lbs.
