A new study has shown that women most desire sex at 11.21pm - but men's optimum time for passion is more than 15 hours earlier at 7.54am.
Despite a busy day in the office or running errands, the fairer sex are most likely to feel passionate between 11pm and 2am.
While men feel at their friskiest first thing in the morning, just 11 per cent of women feel most passionate at this time.
Desire levels for women rise throughout the day and reach their peak between 11pm and 2am.
But just 16 per cent of men want to make love just before they go to sleep.
The study also found that people tend to settle down with partners who have similar sex drives to their own.
