Is Kissing Universal?
Kissing is often portrayed as a universal expression of love, crossing nationalities and languages in media from around the world. However, one study suggests that romantic kissing is not nearly as prevalent as these stories would have you believe. Some cultures don't accept locking lips as a show of romantic affection, going so far as to deem it unpleasant or just plain strange. Research suggests that romantic kissing is more common in cultures with a high degree of social complexity and distinct social classes.
