Kissing holds significant emotional weight in relationships, as it fosters attunement and connection, according to sex therapist Chamin Ajjan. Kissing also serves as a means to assess attraction and compatibility through pheromones and immune system cues. Evolutionary biologist Matilda Brindle notes that kissing may date back 21 million years, with varied styles seen in animals. Iconic movie kisses, such as those from “Lady and the Tramp” and the 2003 MTV VMAs featuring Britney Spears and Madonna, highlight the cultural impact of kissing in storytelling.
