Sorry about your pain
How miserable. I am sorry for your pain. I have never ridden one, but would a recumbent relieve the pressure on your perineum.
I was instructed to cease Aikido, because of the liklihood of a detached retina.
My brother has been required to stop running because it damaged one of his legs.
Sometimes we have unpleasant choices to make, while terrible at the time, can lead to something new and good.
I hope you find a positive solution.
