A brave man who lost his penis to cancer has revealed the remains of his genitals on TV in a bid to warn others of the disease. The man, called Colin, was diagnosed after finding a red rash on the tip of his manhood,  Daily Mail reports.

He was told he would need to have his penis removed to stop the cancer spreading.  And after having the operation, he agreed to bare his groin on ITV's Jeremy Kyle’s Emergency Room.

He was filmed showing the camera his testicles and the 'stump' of his penis, along with scars from where doctors had taken samples from his lymph notes. In a courageous admission, he also said his sex life was ruined.

Colin, 67, said: ‘I lost my manhood, I’m not the man I used to be. It plays hell with your head. 'The sex is gone.’ He told presenter Jeremy Kyle when he first found a red rash on his penis, he thought nothing of it.

He said: 'I got a red blotch, like a red rash but under the skin and at first I paid no attention to it, I thought it would go away but it started itching.

‘So I saw my GP and he gave me some cream. I wasn't worried. I thought it was just a rash because it was just an itch.’

'Then about two weeks later, they referred me to the gum clinic. An ulcer came up which was painful and then I was referred to a urologist. ‘But I still thought the whole thing would go away - like a mouth ulcer. I thought, a bit of bonjela and it would go away.’ The moment he was told he actually had cancer was terrifying, he said.

'The day I was told I had penile cancer, it was like the ground opened up. It opened up,’ he said.

'I had a biopsy and was told the results would come back in three weeks.

'So I went on holiday, came back and the GP said "You have cancer".'

As it hadn’t spread, he did not need chemotherapy or radiotherapy, but had surgery to remove his penis.

‘I think it’s in a jar somewhere in some laboratory,' he said. He now has to sit down to go to the toilet, although says it is not painful.‘Otherwise my shoes get wet,’ he said.

He will able to get a partial erection, and can decide whether he would like to have a prosthesis fitted.

Colin appeared on the ITV show with his wife of 47 years, Sheena.

She said the diagnosis was difficult as her husband found it hard to talk to anyone.

She said: 'He's a very inward man. He keeps everything to himself. I felt like I was being shut out.’

Admitting he didn't want his wife 'feeling sorry' for him, Colin said he found it hard to open up about his feelings.

‘I can be the happiest person in the world but I can be the loneliest person with this. I’ve got to get over it,' he said.

However, the couple said they had been married for 50 years and still loved each other as much as ever.

Colin said: ‘A marriage is for life, not just for a couple of years.'
