For men, Kylie Minogue is the female celebrity most dream of sleeping with, with 18 per cent of the vote, closely followed by Jennifer Lopez at 17 per cent. The study, which involved 50,000 visitors to Durex's websites in 46 countries responding to a questionnaire - 3,500 of them from Britain - also found that when we do slip between the sheets, it appears our partner is often the last person on our minds. Among other findings was that nearly one-third of Britons fantasise about having sex with a celebrity and almost half of British males fantasise about sex with their best friend's partner. Sixteen per cent of women dream of sex with their boss.
