I ride with them. I don't get horrible ones, but I have gotten several over the last year as a result of having to take antibiotics for chronic UTIs. Mine YIs are never that horrible, however, and Monistat provides fairly quick relief.

If you do ride with them, make sure you clean your shorts really well. I know this probably isn't good for the shorts on a regular basis, but I wash them (when I've had a YI) in hot water and put them into a hot dryer.
