'ULTIMATE FIGHTER' STAR Gruesome p***s Injury In HORRIFIC Sex Accident

**WARNING -- YOU CANNOT UNREAD THIS STORY ... AND IT'S GOING TO MAKE YOU CRINGE **

... ESPECIALLY IF YOU ARE A MAN.

... OK, LAST WARNING

... SERIOUSLY, THIS IS MESSED UP.

OK, HERE WE GO ...

MMA fighter Ray Elbe -- who competed on "Ultimate Fighter 9" -- had to be rushed to a hospital in Malaysia earlier this month and required 10 stitches ... after he BROKE HIS p***s during sex.

Elbe told the whole story -- in painfully graphic detail -- on an MMA website ... explaining how he was having sex with his GF, who was "on top" ... when she bounced a little too high, and crunched Ray's erect p***s.

According to Ray, his p***s "fractured" ... and "blood was everywhere." Ray says he immediately passed out from the pain.

Ray says he was rushed to a nearby hospital ... and underwent emergency surgery to close the wound and repair a "slight tear" in his urinary tube.

Elbe says the pain was so severe after the surgery, his johnson was "throbbing with each heart beat."

Elbe says he expects to make a full recovery -- and was ordered to take "anti-erection pills" for two weeks.

The fighter says he learned a hard lesson from the experience -- and will never let his GF be "on top" ever again.

Elbe also explained, "In an attempt to make it up to me ... [my GF] has promised me a threesome of my choice when we get to the Philippines ... which usually has some solid talent."
