For many people, rolling over after a passion session with your partner signals time for sleep and an end to the action but for others, this is simply not the case.

A recent study has discovered that a significant amount of people suffer from a potentially embarrassing condition called sexsomnia, which is when an individual has sex while fast asleep, reports Canada.com.

Researchers at the University Health Network's Sleep and Alertness Clinic in Toronto say that sexsomnia can happen to wide range of people and is often not remembered.

The report, published in the journal of Social Psychiatry and Psychiatric Epidemiology, stated that the condition was first suggested 20 years ago and of those polled 31 per cent were women.

The age range of those citing the problem was also between 15 and 67 years.

"It's more common than we thought," said researcher Dr Nikola Trajanovic.
