Jake Paul has revealed he is on a self-imposed sex ban with girlfriend Julia Rose ahead of his rematch against Tyron Woodley.
The 24-year-old YouTuber-turned-boxer faces Woodley in Florida on Saturday, December 18, after Tommy Fury pulled out of their scheduled bout.
Paul and Woodley squared off inside the ring in August, with Paul taking home the win after earning a split decision victory.
And it seems as though he's doing whatever it takes to emerge victorious once more.
Watch Jake Paul's interview with Graham Bensinger here:In fact, Paul has insisted he has been refraining from having sex with girlfriend Rose, who he has been dating on-off over the last couple of years.
Despite the harsh self-imposed ban, Paul has joked that he's "messed up" on occasions.
In a new interview with journalist Graham Bensinger ahead of his fight, Paul said: "It's different for each fighter. A lot of fighters are affected by it, including myself and I'm 100% sure [it's not all mental], I don't believe in placebo, I have to experience things for myself.
"I've only messed up on occasion once or twice because it's noticeably different, and I take more punishment in sparring if I do that."
"My coach BJ [Flores] will be like 'did you have sex last night?' And you can just tell without me saying anything," he added.
Paul's trainer BJ Flores added: "He's not as good, he's not as quick or as fierce or aggressive. It's obvious to a guy who has been around boxing for 33 years so I see it very quickly and he always comes clean.
"Ancient warriors deprived themselves of certain things before they went to battle and it's important that Jake sacrifices and deprives himself of certain things before he goes into battle."
"If not having sex for a little while will make us half a percent better, then I'll take it," he added.
Elsewhere in the interview, Paul said he is suffering from mood swings, memory loss, and slurred speech less than two years into his boxing career.
"I notice it in conversations with like, with my girlfriend or friends, like, not remembering something that I should be able to remember that happened a couple days ago," he explained.
"Sometimes in my speech, where like every hundredth or two hundredth word, I'll mess up or, like, slur. Which I didn't do that before."
The YouTube star-turned boxer claims he's endured anywhere between 20 and 30 concussions in his lifetime, though "it's really hard to say" exactly how many.
