A person's idea of what an orgasm looks like may depend on where they live. Researchers have found Western and Eastern cultures generally agree on what our face looks like when we're in pain. But when it comes to what our faces look like during an orgasm, that's where the two cultures differ. University of Glasgow researchers created a computer program that could mimic a variety of facial expressions. For the simulated faces, the researchers used a core set of 42 movements.
