Penile fracture?

Patient: His penis slipped out of my while I was on top, and I accidentally landed on his penis. He groaned in pain and lost his erection. He was able to regain his erection a few seconds later, but then lost it again. He also noticed slight darkening of the color around the tip of the penis and the shaft. That’s all I know because now he’s furious at me he won’t talk. May I know if he has just had a penile fracture?
