Mike Tyson has admitted fighting is "orgasmic" and gets him erect.
It comes as he prepares for his return to the ring when he meets Roy Jones Jr with a date in November pencilled in.
The former heavyweight champion has been vocal since he hung up his gloves and is close pals with Joe Rogan.
He has been on his podcast, the Joe Rogan Experience, several times and has often spoken candidly about his controversial life.
At times, Iron Mike has broken his silence on the psychological torment that comes with stepping in the ring.
But he has also admitted that fighting has left him feeling aroused, as well.
“It’s orgasmic sometimes,” he said.
Following up, he asked Rogan: “What does it mean when fighting gets you erect?
“Well that’s how I’d get when I was a kid. Sometimes I’d get the twinkle.”
The New York-born fighter has not fought since 2005 when Kevin McBride beat him in seven rounds.
But he will meet Jones Jr in the ring in an exhibition match spanning eight rounds for charity.
However, the match has been thrown into jeopardy after Tyson's opponent threatened to walk out due to the change in timing.
"I’ve had to cancel other stuff to be out here, it’s upset my calendar, I’ve got to change things," the American told the Daily Mail.
"That’s why we have to table bulls**t now. That’s the biggest issue, I’m not a full time boxer anymore so I do other things to make an income.
"If I can’t do other things then I should be compensated for that, because it changes the schematics. It’s not acceptable.
"We’re trying to figure something out, my lawyers is (sic) talking with their lawyers, trying to figure out ways to make it a better situation so that I can compensated for it, that is more beneficial for me to do.

"If they don’t make it make sense, it (the fight) would be off.
"Why would I change the date and mess up the rest of my year when I agreed to September 12.
"They said they wanted to get a crowd, if you want to get a crowd, that’s a different type of money. If you want a big event, that’s a different type of money.
