Szilveszter felt self-conscious about the size of his penis, so decided to open up about his insecurities to a friend.
"I was talking to my friend about wanting to lose weight so my penis would look bigger when he replied, 'You don’t need to lose weight – I can help you,’” he explained on the latest series of TLC show Extreme Beauty Disasters.
Szilveszter’s friend then convinced the father-of-one that it was a good idea to inject hot Vaseline into his penis, in a bid to make it bigger.
“My friend injected in my penis Vaseline. Afterwards I was happy as it looked bigger.”
But, unfortunately for Szilveszter, the effects came at a price - and just a few months later, he began experiencing problems.
“It was painful and bleeding. I went to my GP, but he said he couldn’t help me.
"It hurt so much I had to stop having sex with my wife. It was the worst mistake of my life."
Szilveszter turned to Extreme Beauty Disasters resident plastic surgeon Dr Vik Vijh who said there was hope he could be cured - but it wouldn't be easy.
Dr Vijh explained: “Your body has formed scar tissue around the Vaseline because it's a foreign body, your body is trying to ward it off and it gives you these painful lumps, it will soon start to ulcer through the skin.
“The other problem is the foreskin is swelling and splitting - the foreskin is 15 times more swollen than should be.”
The cosmetic surgeon ‘skinned’ Szilveszter’s penis like a banana, and removed the scar tissue.
And, as a result, Szilveszter now has a fully-functioning penis - and has definitely learned his lesson.
He said: “I am much better. It has healed well, it's painfree and working. I can have sex with my wife again.
“Many people said we can't help you. Dr Vijh did a perfect job, he has changed my life.”
