London, Apr 16 : A bizarre sex craze has landed many Jamaican men in hospitals, after they got their willies fractured while indulging in a fast and rough intercourse, called "daggering".

Doctors have reported that the number of such cases has skyrocketed in a year after a rise in so-called "daggering".

In their opinion, the injuries occur during the fast, rough intercourse and can even cause permanent damage.

"We have noticed an increase," the Sun quoted a doctor at Kingston Public Hospital on the island as saying.

He added: "During very rigorous intercourse the man can hit the woman's pubic bone and sustain a fracture. There is a loud popping sound, excruciating pain and swelling." (ANI)
