OnePoll.com questioned 3,000 people to come up with the finding that an average man thinks about sex 13 times a day compared to an average woman.
Tests showed that comparatively an average woman thinks of sex just fives time a day.
And, even though men think of sex at least a dozen times a day, they have it just twice a week, or 104 times a year.
"Men are well known for thinking about sex a lot but to find out exactly how often they do is staggering," the Mirror quoted the market research firm as stating.
It added: "It seems blokes have sex on the brain whether they are in a dry spell or jumping between the sheets on a regular basis."
However, three quarters of men were happy with the amount of sex they were getting.
