Roberto Esquivel Cabrera, 54, from Saltillo, Mexico, has a penis measuring a colossal 18.9 inches.
He made headlines worldwide in 2015 after a video went viral showing him weighing his colossal member to prove its authenticity.
His half-metre penis smashed the record previously believed to have belonged to American actor Jonah Falcon, whose penis was 9.5 inches flaccid, and 13.5 inches when erect.
Speaking to Barcroft TV, Roberto said: "I am famous because I have the biggest penis in the world.
"I am happy with my penis, I know nobody has the size I have. I would like to be in the Guinness Book of Records but they don’t recognise this record."
But despite his pride, members of the medical community have urged him to at least consider a penile reduction.
Doctor Jesus David Salazar Gonzalez said: “We have advised him 'Mr Roberto, the best thing for you is that the doctors give a normal shape to your penis so that it doesn’t hurt you, in order to have sexual relationships, in order to have children.'
"But he doesn’t accept it, he’d rather have a penis bigger than the rest of the people.
“In Latin culture whoever has the bigger penis is more macho.
"It’s something that makes him different to the rest of the people and makes him feels special."
Doctors recently did a thorough examination of Cabrera’s penis, confirming suspicions that the bulk of his nearly 20 inch penis is foreskin.
Radiologist Jesus Pablo Gil Muro said: "Our findings on the CT scan were that he has very large foreskin, it goes almost to the knee.
“The glands themselves are only six to seven inches from the pubice. It doesn’t go all the way through the foreskin.
“The rest of the tissue found there is foreskin and blood vessels and some inflammation of the skin that he has made through the years."
Doctors have also been able to offer some insight in just how Roberto’s penis became quite so large - they say he has been stretching his penis with weights since his teens.
"He was obsessed with the penis length,” Dr Gonzalez said.
“He began with this enlargement since he was a teenager, wrapping some bands around his penis with some weights and trying to stretch it."
The sheer size of Roberto’s penis causes him a number of health problems, including frequent urinary tract infections because not all his urine escapes his lengthy foreskin, and he keeps his colossal member wrapped in bandages to escape chaffing.
He is also unable to sleep chest down and has to put his penis on its own pillow to escape discomfort during the night.
An active sex life is also off limits for Roberto as his penis has too much girth to have intercourse.
He said: “Some people ask me if I put some condoms on it and the answer is: I cannot. I can never penetrate anyone because it is too thick."
While living in the USA, Roberto did attempt to have sex twice, but the first woman backed out as soon as she saw his penis and the other one had to stop because it was too painful.
Roberto says his penis is a “disability” and stops him working - forcing him to rely on food banks to survive.
"I cannot wear a uniform like anybody in the companies and also I cannot get on my knees,” he said.
"I cannot run fast and so the companies think badly of me. They say that they will call me, but they never do."
According to Roberto, after initially dismissing his claim, the government has now recognised him as disabled.
“Every four months they give me some economic assistance but it is not enough,” he said.
"I visit the food banks everyday to take my meals at 12 ‘o clock.”
Another downside to having such a gigantic penis is that many people believe it is a hoax.
He said: "Sometimes when the people ask me if it’s real or not, I ask them ‘Do you want to see it?'"
Dr Gonzalez added: “It’s real, he has allowed us to touch it and you can see that it is - he allowed us to touch it to confirm.”
Dr Gonzalez and his team also believe there may be a neurological explanation for Roberto’s desire for an ever-larger penis.
“In an encephalogram we observed that he had an alteration at the right temporal lobe,” he said.
“This alteration gives people exotic ideas, for example they tend to speak a lot about religion or they are very persevering and stubborn.
“Like these women who go for bigger breasts, or men who want bigger gluteals, he modifies his body in the same way."
However, there is a darker side to Roberto’s past - while living in America he was convicted on a string of indecency charges.
They include a felony assault charge for exposing himself to two underage girls, a conviction he appealed unsuccessfully.
He was forced to leave the US in 2001 but has now set his sights set on returning.
An adult entertainment company offered to pay for a reduction, but Roberto refused and says his goal is to to meet the right woman - and possibly launch himself as a porn star.
He added: "I am happy with my penis and I wish to go back to the USA and spend the rest of my life over there.
"I don’t feel sad because I know in the USA there is a lot of women. One of them will be the right size for me.
"I would like to be a porn star and I think I would make a lot of money over there.
"And the people are not like over here, they are more liberal: they don’t care about what I have in my pants.”
