A recent study published in the Proceedings of the National Academy of Sciences (PNAS) of the United States of America has shattered the age-old myth that the facial expression you make when you’re in pain, and the one you make when you orgasm, are the same.
To come up with this conclusion, the researchers from the University of Glasgow in Scotland analyzed various facial changes that people (particularly Westerners and East Asians) make while experiencing pain and orgasm.

Next, they asked 40 men and 40 women to determine if the facial expressions showed happen when someone experiences “pain,” “orgasm,” or “something else.” They then used the results to build clearer models and then asked another 104 people to analyze the facial expressions.

The researchers discovered that people’s faces do react differently when in pain and in pleasure. Specifically, when experiencing
Here’s a more detailed depiction which includes the specific facial expressions:
“Pain is represented with similar face movements across cultures, whereas orgasm shows differences,” the authors concluded.
To further explain their findings, the researchers also released animated video representations which showed how the face reacts when in pain and when
