Mattress Advisor found that on average, after a one night stand guys put on fresh bedding after 18 days compared to 2 days for women.
However, they found men are more likely to change their sheets if they predict sex is going to be on the cards.
It's said 43 per cent of men will change bedding before a night out if there is a possibility of sex later on, while only 33.4 per cent of woman will.
But if sex is guaranteed this increases to just under 49 per cent for men and 39.1 per cent for women.
