7:37pm on Sat night means SEX hour!

Despite the fact that many of us have little time for spontaneous sex the survey suggests that when we are planning a hook up we like to be romantic with 62 per cent couples regularly have 'date nights' - specific days of the week they keep free for romantic fun.

On a date night, 88 per cent of couples usually end up having sex. Research also found that six out of ten of us have booked a hotel getaway specifically to get some time alone for sex and intimacy.

The survey also revealed that its not just the time of day that can affect our libido, our sex drive varies depending on the time of year too.
