Three male German business students offer sex service to stressed out female students (it’s proven to improve grades, they claim)

Three German students are offering a gigolo service to female students which they claim could help their clients beat stress and improve their grades.

The three students, from University of Mannheim in south-western Germany, are offering their services for free and claim they are champions of female sexual emancipation.

'We are focusing on female students in particular, because they generally come out badly after one-night stands,' said Christopher, 21, to Der Spiegel.

'What's more, girls who just want to have some fun are often labelled as sluts.'

Helps with the essays: That is the claim made by three German students who have started a free gigolo service for female students

The trio, who do not want their real names published and are identified by Der Spiegel as Christopher, Oskar and Markus, have plastered their university's campus with ads for their service.

They have dubbed their project Bib:Love - a play on the German word Bibliothek, meaning library - and their slogans promise 'Good grades through Good Sex'.

Although many of their fellow students greet the signs with roars of laughter, the men say they've already had lots of emails from students who want to find out more.

They tell correspondents that regular exercise, like lovemaking, brings health benefits and helps with studying.

Female students who are drained and fatigued from evenings spent in the library are encouraged to send an email. Then one of the trio will meet with them.

If the chemistry is right, the meeting ends in sex. But the men reserve the right to withdraw their service if their client's appearance is not promising.

Christopher, Oskar and Markus claim they have so far received 82 messages at the Bib:Love email account.

Of these, they say, nine have resulted in bookings. They claim they have had five one-night stands through the service so far.

Good clean fun: The boys admit unusual sexual practices are not catered for

Lisa, 23, was the first. Although she too prefers to be known via a pseudonym, she told Der Spiegel there was nothing negative to report.

The men behind Bib:Love present themselves as service providers with a sense of humour. The idea for the project came to them during a drunken night last autumn.

However, Der Spiegel points out, despite their claims to be champions of female sexuality, the free brothel service they are offering is far from revolutionary.

Christopher admitted to the paper that unusual sexual practices are not catered for.
