I know this may be easier to ingest, than to digest, but here we go.. I've been there, and done that; I had hard flaccid and dick numbness for pretty much a week, after my first 2 weeks of PE. Guess what? It went away. You just need to give it time with more rest. and next time, read as much as you can before you jump into PE! I look at my injury as a shocked state, like I literally shocked my dick with the exercises it's never been through before. 6 weeks later, I'm PE'ing wonderfully.
