I believe you Weed UK. I've heard of that before, I think they call it a penile fracture or something like that. Supposed to hurt like hell.

Only pain I've ever had as a result of sex(well, other than an std..but that's another story) was from what I call cock glue. Any guys out there get it other than me? You know, you've still got some cum or precum in the tubes when you pull up your pants. A little bit comes out then dries up, basically gluing the tip of your dick to your underwear. Then it just waits silently, until the next time you have to go and take a piss. You walk into the bathroom, pull down your pants, and then...."holy crap that hurts!!"
