The X-rated findings will infuriate bosses as it is revealed that almost a fifth — 17 per cent — of office staff have enjoyed full sex before clocking off.

Some encounters were with regular partners and others with colleagues, the survey showed.

David Minns, of, er, respected pollsters saucydates.com, which carried out the research, said: “A common theme is people enjoy the thrill of having sex while they’re meant to be ­working.

The poll of 20,000 workers found that 26 per cent of couples had used a private office, making it the most popular spot to get frisky.

One in seven frolicked in the store room, 13 per cent in the loos, and a brave five per cent in the lift.

Encounters were most likely to happen when people were working late and the office was empty.

But some reported having enjoyed secret sessions during the hustle and bustle of the working day.

“As you’re constantly around them, you get to know them more. It’s easy to communicate as you work with them and the barriers you have in your normal dating life aren’t there.”

But she warned against office affairs as mixing business with pleasure was fraught with problems if the romance did not work out.

She said: “Falling for someone and being sexually attracted to someone is very powerful but I would urge people to keep it outside of work.”

Her tips for managing an office romance include not dating the boss, steering clear of illicit affairs and always keeping things in the office strictly professional.
