A worrying one in four women would rather partake in an outdoor activity than stay home for some loving with their partner, with four in ten opting for a shopping trip rather than an afternoon in bed.
Even wedding night sex has taken a knock, with a third not managing to consummate their marriage on the night of their big day.
And half of those who have been married for 20 years could go without any bedroom action at all, the research by First magazine revealed.
But this does not mean that women are going off their long term partners, with 72 per cent of wives giving their partner at least seven out of ten in terms of sexual attractiveness.
Anjula Mutanda, a relationship psychologist, told the Daily Mail: "Considering that sex is a healthy part of a loving relationship and is an important way of physically and psychologically connecting with your partner, something is clearly wrong.
"Having no sex at all creates distance and resentment. A once loving and tactile relationship becomes the equivalent of living with your brother or sister."
