My penis has got a dent in and i carnt get an erection.

Patient: I’ll start from the very beginning.About 6years ago I was having sex with my girlfriend with her on top as she was on a downward motion my penis came out and was bent double and it really hurt,.Everything was fine after up until around about 2-3years ago when an indentation appeared in the side of my penis, it has got worse as times gone on and now there is a dent clearly visible and I cannot get an erection.I am 40 years old,just got married, I am sexually attracted to my wife so that’s not the problem, I know it’s to do with the ‘DENT’.Please help me I feel to embarrassed to go to the Dr.
