How to tell if a man is good in bed - just by looking at him

The length of a man's fingers determine whether he will last a long time in bed or be likely to suffer from premature ejaculation, new research has found.

Scientists have discovered a new way of telling how long a man will last in bed - just by looking at his hands.

Now you’re all studying your partner’s hands, this is what the experts have come up with.

Apparently if a man’s ring fingers are the same size or shorter than his index fingers he will last longer in bed.

But men with longer ring fingers are more likely to put on a disappointingly short performance.

And the new finger findings are all connected to testosterone.

Up to one in three men will suffer from premature ejaculation at some point in their lives and it could all be down to the size of their fingers

Dr David Goldmeier at Imperial College London found the more testosterone a baby boy comes into contact with in the womb, the longer his ring finger will be compared to his index finger.

The expert explained that high levels of testosterone exposure could harm brain receptors that control ejaculation.

Previous studies have suggested premature ejaculation, which affects up to one in three men at some point in their lives, could be put down to genetic factors or rushed early sexual experiences.

Other studies have shown that men with longer ring fingers have larger penises, are at a lower risk of contracting heart disease and are more successful athletes.

But statistically they are more likely to drive too fast, get prostate cancer and be autistic.

Turkish scientists tested 65 men with a history of premature ejaculation and compared them with the same number that had no problems.

They told The Sun: “Foetal hormone exposure may be a new risk factor for lifelong premature ejaculation.”

Men suffering from premature ejaculation typically last less than a minute while those who aren’t affected will have sex, on average, for between five and seven minutes.
