But when it comes to the office Christmas party, these guys certainly know how to let their hair down.
A new survey by Ann Summers reveals that a whopping 39 per cent of people admit to having sex at the Christmas party and the biggest culprits are those who work in IT and HR!
The survey of 2,000 British adults by the leading lingerie and erotic retailer, uncovered our frisky festive habits.
Half of us admit to snogging a colleague, while senior managers are most likely to get their freak on, with 65 per cent claiming to have had sex at the office shindig.
And while our favourite place to get jiggy with a colleague is the car park (25 per cent), 16 per cent took the risk of doing it on their boss' desk.
Somewhat worringly, one in 10 people had sex in the office canteen.
We just hope those tables were wiped down properly afterwards!
