Men think about sex almost 5,000 times a year – but only get down to doing it 104 times, a new study has found.
Almost a third even admitted it is often the first thing they think about when they wake up in the mornings.
In comparison, women think about sex just five times day – or 1,825 times a year.
But when it comes to actually having sex, men have to make do with it an average of just twice a week, or 104 times a year.
A spokesman for market research company www.Onepoll.com said: ''Men are well-known for thinking about sex a lot, but to find out exactly how often is staggering.
''It seems blokes have sex on the brain whether they are going through a dry spell or jumping between the sheets on a regular basis.
''They can't even get away from the sexy thoughts when they first wake up in the morning.
''So when you catch your man staring into space, you know what he's likely to be thinking about.''
The study of 3,000 people also showed that despite the difference in the amount of times men think about sex and actually do it, almost three quarters claim they are happy about the amount of sex they were getting.
But just 58 per cent of women said the same.
And 43 per cent of couples also admitted arguing over who instigates the lovemaking, with men most likely to make the first move.
Researchers also found one in three guys think a candlelit dinner is the best way of getting a woman in the mood, followed by a relaxing massage.
But women are more likely to play romantic music or cook their partner's favourite meal to try and get them into bed.
Researchers found the average male turns their thoughts to sexual intercourse 13 times a day – a total of 4,745 times every year.
