The poll, commissioned by One Condoms, delved into how the festive period can diminish the sex lives of thousands of happy relationships.
Despite most admitting that they would seek quieter sex (44 per cent), the findings showed a third (38 per cent) would have less sex.
Just 6 per cent of respondents, who were between the ages of 18 and 65, revealed that they would try to have more sex this festive period.
Annabelle Knight, a certified British couples counsellor, told MailOnline that ‘family staying can be a hinderance to our sex lives’.
She added: ‘Research shows many people will be finding ways to enjoy steamy-but-sneaky nights by embracing quieter positions over the festive period.
‘Cowgirl and doggy can be noisy, hand-over-mouth is only liked by some, but missionary and spoon-sex are seasonal favourites because they allow for all the fun.’
However, Ms Knight, who has given sex advice on Big Brother’s Bit on the Side and ITV’s This Morning, said those positions have further benefits.
She added because spooning and missionary are quiet they avoid any ’embarrassing exchanges over breakfast the next day with a relative’.
Just a quarter admitted they would have less sex because ‘there is family around’ – and 32 per cent said they would actually have more.
The survey also revealed that a fifth (21 per cent) of people would make special arrangements about sex to cope with family staying.
And more than a third (38 per cent) would avoid making love for the entire festive period – with New Year’s Day being the least popular day.
