While you may be honestly making "love" to your partner, it turns out nearly half of men and women fantasise about someone else, possibly a colleague, while having sex.
According to a survey 46 per cent of women and 42 per cent of men let their imagination "cheat," and while it has been men who are usually held guilty of eyeing up attractive female colleagues, the poll showed women do the same, reported the Mirror.
Sex toy retailer Lovehoney's survey of 1,300 people also found these fantasies sometimes turned into reality, with 8 per cent of women and 2 per cent of men admitting to have had sex with their boss.
