The former NBA legend snapped his manhood during s3x on three separate occasions over the years.
The first unfortunate incident happened during a romp on a boat in Dallas, Texas following a day of "drinking and partying".
In a video for Viceland the star revealed: "Me and my girlfriend, we were on the back of the boat in a king size bed and she said 'I think I'm going to try something different. She told me to walk over there and told me to run and jump in her p." Continue lol.
After taking a leap Dennis, 55, said heard a crunch and saw "blood everywhere".
He said his partner screamed: "Oh my God, he is dead, he is dead. I have killed him," before he reassured her: "No honey. I just broke my d**k."
Dennis said the next agonising incident happened while he was playing for the Detroit Pistons and was wooing a lady called Tracy.
After enjoying a romantic dinner the pair retreated to his hotel room where they engaged in a s3x act which went horribly wrong.
Dennis told the camera: "Crack, another one. I couldn't do anything."
Recalling the third time, Dennis said: "It was in New York. Same thing. We go to the hotel room and we're having s3x and it ended up breaking.
"We go to hospital and my girlfriend is like, 'Well you know, he has a problem with his p3nis.'
"The woman comes up and says 'Oh, I'll be right back'. She brought another doctor in, and then another one. I swear to God she just kept bringing people in.
"They told me I had a contused penis."
Dennis claims the following day his girlfriend received a call from a nurse asking for $25,000 in exchange for the X-ray pictures of his manhood.
"Okay then do it," Dennis claimed his girlfriend replied.
