New research from Abertay University published on Valentine's Day reveals that what makes a "good kiss" has far more to do with our imagination and internal emotional world than the physical act itself. Published in the journal Sexual and Relationship Therapy, the study shifts attention away from the physical act of kissing and toward the internal thoughts and fantasies that influence how people experience it. While many people assume kissing helps spark sexual chemistry, these assumptions have rarely been tested scientifically.
