Yes, romance can include kissing.
Romance is a broad term encompassing a range of expressions of love and affection. While kissing is not a mandatory component of all romantic relationships or interactions, it is often considered a significant and common element, particularly in Western cultures.
Kissing is viewed as a physically intimate act that can convey deep emotions. The referenced text highlights that romantic kissing is considered a very effective method for solidifying the bond between partners, with both men and women reporting it as the type of physical affection that is "most expressive of love." Thus, while romance can manifest in many forms, kissing is frequently perceived as a powerful symbol of romantic love and connection. Not all romance will involve kissing, but it can be a key part.
