Over the last year, many men on Reddit have been discussing a rather unusual topic.
It's something known as 'jelqing', and it's an unpleasant technique that has been believed to help enlarge the penis, by repeatedly stretching it while semi-erect.
This process is done over a lengthy period of time and it's thought that each stretch makes a tear in the penile tissue, allowing scar tissue to fill in the space, thus eventually making it look bigger.
And while some claim to have seen the desired result from doing just this, two medical experts have warned that it's likely to do more damage than good in the long run.
Two urologists have revealed that they too have seen a rise in the number of patients asking about jelqing.
But they definitely haven't been advising them to give it a go.
Speaking to MailOnline, Dr Jamin Brahmbhatt, a certified urologist at Orlando Health, said: "Those repeated, traumatic movements can translate into scarring, but can then translate into Peyronie's Disease, where you form a plaque, that can be associated with erectile dysfunction and pain as well."
That scarring can start to curve the penis, causing erections and penetration to become difficult - and in some cases impossible.
"It's a complete waste of guys' time," he continues. "It can be very painful, and sometimes the scarring can take three to six months of even a year to build up for you to notice the change.
"So you may think you haven't seen any negative side effects, but it may just take some time."
And he's not the only one who feels this way.
Dr Premal Patel a urology fellow at the University of Miami agrees and encourages any men with concerns to speak to a medical professional, as there is no scientific basis for jelqing and it could be very dangerous.
So there you have it folks, just don't even bother.
