Sex = Heroin Researchers Say
 

Volunteers had brain scan during sex for experiment

Volunteers agreed to have sex while having their brains scanned for a Dutch scientific study.

They had to keep their heads perfectly still while having sex and had to finish within seven minutes.

The experiments were part of a study by researchers at Groningen University into sexual problems.

Professor Marc Holstege said the PET-scan would not have worked if the volunteers had not managed to meet the conditions.

He told De Telegraaf: "But as we asked them all to practise before the scan was made, they all succeeded. The men were also asked to ejaculate within seven minutes. And that was no problem at all either."

Among the study's findings was that an orgasm has the same effect on the brain as a dose of heroin.

Prof Holstege said the results of this survey could help develop a medicine to treat people with mental sexual problems in the same way that viagra helps people with physical problems.

Cumming under seven minutes while not moving your head??? Oh well,I guess thats normal sex for some people.After all,the Brits have to do it while keeping a stiff upper lip.

I wonder if they had fun?

I cannot imagine not moving my head during sex!
