Have you ever wondered what you look like when you hit that perfect peak during the 'act of which we shall not speak'?

Cutting it short (which I obviously haven't so far), I'm talking about what your face looks like when you orgasm.

Well, for want of a better subject to study, Spanish scientists have analysed 100 voluntarily uploaded videos of people’s faces during orgasm. These were the most commonly made facial expressions:

•    92 per cent closed their eyes
•    67 per cent dropped their jaws
•    48 per cent frowned or lowered their brows
•    44 per cent parted their lips

That makes the most common pair the old jaw drop and closed eyes (36 per cent).

Scientists speculate that these expressions are reflexive – meaning you have no control over your expression due to a release of muscular tension as you approach orgasm. So now you can relax and embrace your orgasm face!
