Yes, penis can break guys.
The human penis has no bone, and it's supposed to be spongy, no?
It normally happens during sexual intercourse, when you perform an unimaginable acrobatic on your bullish pole, a flying leap perhaps, instead of a simple penetration. The girl-on-top position is equally risky, for it constitutes the most cases reported for penile fracture during sexual intercourse. Missing the bullseye and bending your rigid genitalia against the mattress can be extremely agonizing, too.
And when your throbbing manhood breaks, you could literally hear a popping or cracking sound. The pain that follows would be ludicrously excruciating, and the your herculean kraken would deflate immediately. Your penis would become swollen, bruised, and discolored, and you probably can't urinate for the next few days until you seek medical attention.
By the way if all of the above didn't tense you up, you're probably heartless, or penis-less. Or both.
According to a paper written by urologist Andrew Kramer, published in a recent issue of Journal of Sexual Medicine, half of the penile fracture he saw between 2007 and 2011 were sustained during an extramarital affair. Others, he said, were suffered while making out in extraordinary locations--cars, elevators, public restrooms. He concluded that penile fractures "seem more likely during sex under stressful situations."
