Re: injured and now i cant get an erection
YURPS.. that sounds like you broke your penis. Look it up in the web, there's lots of articles about it. The situation you just described is what often causes penis break. It requires medical treatment NOW.
I found about that when i had my own injury and i was despararetly looking for help. I didn't have penis break, but i had nerve break which also caused impotence for months.
If you don't see anything physically wrong.. you probably had nerve damage like me WHICH is even more difficult for doctors to do or know anything about. But if there's obvious blood and weird colors in your penis.. then it's penis break. GO TO the emergency
