Channing Tatum thinks about burning his penis "every time" he is cold.
The 35-year-old actor suffered the accident while filming 2001 movie 'The Eagle' after an assistant poured too-hot water down his wetsuit in a bid to keep him warm while shooting in the Scottish Highlands and he still has flashbacks to the agonising moment.
He said: "Every time I'm cold I think about it. It's not one of those traumatic experiences that you block out. No, it's real and it's never ever forgotten. Though I still look at it as one of the funniest stories - just not one of the funniest experiences.
"(I was) just trying to hold my sanity together, just crying, just screaming in pain."
And Channing - who has two-year-old daughter Everly with wife Jenna Dewan-Tatum - was told by doctors that the pain he was experiencing was a "good thing" as it meant he wouldn't lose the use of his manhood.
Speaking to GQ magazine, the 'Magic Mike XXL' actor said: "I'll never forget what the medic said. He was this sweet, older guy and he was like, 'I know it's no consolation now, mate, but it's a good thing it hurts so much, as otherwise you've got nerve damage - and then you've really got a problem.'
"There's nothing more humbling than sitting with your very burnt, blistered manhood, and a bunch of Scottish emergency room guys staring down at your junk. I remember thinking, 'This is the worst Friday night ever.'"
