Kegeling alot, seemed to have caused ed. permanent or just needs rest?

More to it: Kegel exercise for men is generally in response to having a problem. Without a problem, there probably isn't a role for it at age 20. http://www.mayoclinic.org/healthy-living/mens-health/in-depth/kegel-exercises-for-men/art-20045074 Then, it seems likely that over exertion of an unused muscle group could cause short term problems that a bit of rest will help. cannot say in your partic. case.
