Elderly man dies during sex while still physically attached to prostitute

An elderly Chinese man died while having sex with a prostitute, according to several online media outlets.

Disturbing footage of the pair being wheeled out of an unidentified building in China has emerged online. It was first shared on Chinese video sharing platform Miaopai before being shared by other users on LiveLeak, The Daily Mail reported.

The clip shows paramedics wheeling a supposedly dead body on a hospital stretcher - with a moving person still on top. Both of them were covered with a blue blanket.

Bystanders could be seen watching on in horror.

The two were reportedly sent to a hospital to be surgically separated, according to online news website Inquisitr.com.

Although uncommon, it is still possible to die during sex and it can also be caused by an increased strain on the heart, The Sun reported. This strain can lead to a heart attack, which is more common among men.

Another possible occurrence during intercourse is penis captivus, where two sexual partners become stuck together during sexual intercourse. Vagina muscles clamp down on the penis harder than usual, according to The Daily Mail.

Dr John Dean, a UK-based sexual physician, told the BBC: "The muscles of the woman's pelvic floor contract rhythmically at orgasm. While those muscles contract the penis becomes stuck and further engorged."

He also said the man can "withdraw" once "the vaginal muscles relax" and "the blood flows out of the penis."

It is still unknown as to what happened to the pair in China.
