Penis repair after injury?

[rraa]

Hi, i have already posted this question on another forum but i am desperate for a reply.

hi everyone, i am really worried about my husband, we injured his penis twice, a year ago, and a few months ago.  he would not let me talk about it and said it was absolutely fine.  there apparently was a pop but is erection remained, there was no blood, bruising or swelling.  he now says he can feel it kind of crunching or cracking.  i warned him of all i had read but he wouldnt hear of it.  now we are experiencing problems and finally he has admitted that something has to be done.  but i am worried it is too late?  he can still get an erection, but it isnt anywere near as hard as it used to be and also he is experiencing loss of sensitivity.  anybody with experience of this, i would be extremely grateful if you would advise me.  i am going out of my mind with worry for him, his physical and emotional health are more important to me than anything.  thank you
