Most (66 per cent) claimed that they weren't fussy about what day of the week it was, but 18 percent admitted that Saturday was a favourite day for sex.

That doesn't mean the respondents were talking about their partners, an equal share of men and women admitted to having had at least one affair, with 37 percent saying they had cheated on a partner in their lifetime.

Sexpert and MailOnline blogger Tracey Cox says: 'Bathrooms offer privacy and having a bath or shower together can be super sexy. But it also works well if your partner has hygiene problems. I often suggest people have a bath or shower with their partner before sex if they're worried about body odour. 

'People who are squeamish about sex often like doing it in places like the shower because it feels 'clean'. 

'Sadly, the most common place and time for most long-term couples in Britain is to have sex at 10.24pm on Saturday nights ... in the bedroom! Though it's not all bad: the kitchen bench is also a favourite.'
