A British tourist has undergone medical treatment after he ripped his penis during a ferocious sex session with a Thai prostitute.

The unnamed holidaymaker in his 30s called emergency services while yelling incoherently down the phone on Saturday night.

Paramedics rushed to the hotel in the notorious red-light city Pattaya in eastern Thailand amid fears there had been a murder or an attack.

When they arrived the man was wearing shorts and there was a Thai prostitute in the room with him.

The white bed sheets were covered with a large amount of fresh blood.

The panic-stricken man explained to the team that he was having sex so hard that his frenulum - a small piece of skin that connects the foreskin to the penis - had ripped.

Rescue volunteers gave him first aid at the scene after he refused to go to the hospital because he was so embarrassed by the injury.

One of the volunteers who attended the scene said they first thought they had arrived at a crime scene because the man was screaming so loudly and there was a large pool of blood.

Khun Tumrin said: 'I picked up the phone and heard he was screaming so loudly. I only understood that he wanted us to go there as soon as we could.

'When I entered the room and saw the bed sheet I first thought there had been a stabbing.

'It was a big relief when we realised what had actually happened. He explained it was because he was having sex too hard with his escort for the evening.

'He was in a lot of pain but we thought it was very funny.'
