BRAINY babes find it harder to have an orgasm – because they are too busy thinking, a study claims.

The German survey found that the more educated a woman was, the less likely it was that she would be satisfied by sex.

In the study 62 per cent of women who had completed their education said they often had problems achieving orgasm.

Only 38 per cent of women with a lower educational qualification said they had such problems.

The study conducted by a German lifestyle website surveyed over 2,000 women between the ages of 18 and 49.
