I just read this news article and wow it has potential.

I came across this article today:
Gizmodo: A Man's Penis Broke Vertically During Sex—an Apparent Medical First.

So lots of story potential there especially if you expand it past the realms of realism but I really found it funny that it was a ‘transverse’ fracture.
