There's a time and place for wild sex, but you don't want to become too energetic and risk giving your man a penile fracture. When I saw this happen on a recent episode of Grey's Anatomy, I thought they were joking. I mean, there's no bone in the penis, so how could it become fractured? This rare injury actually involves the cylinder in the penis known as the corpus cavernosum, the part that becomes engorged with blood when a man has an erection. When the lining of this cylinder ruptures, it's known as a penile fracture. It's apparently an extremely painful injury that may be accompanied by a popping sound, immediately followed by bruising and loss of erection. The urethra may also be damaged, and a guy may notice blood at the opening of his penis. This is not something that will remedy itself with ibuprofen and a bag of ice — immediate medical attention and surgery is necessary, and if the guy doesn't get help, he can suffer permanent damage to his business.
A penile fracture can happen during sex when the woman is on top, when the penis becomes overbent, or if too much pressure is applied. It can also happen in non-sexual situations — anytime a guy suffers trauma to his penis while having an erection, he's at risk for a penile fracture. Like I said, this is a pretty rare injury so I wouldn't worry too much about hurting your man, but it is something to keep in mind.
