What is kissing horizontally?

Kissing horizontally, also known as a horizontal kiss or a lying-down kiss, is a type of kissing where both people are lying down. This type of kiss can be seen as more intimate and romantic, as the couple is in a vulnerable and close position. Horizontal kissing can also allow for more physical contact and closeness between partners as they are able to hold each other while kissing. This type of kissing can often be more relaxing and comfortable for both individuals, as they can fully focus on each other without the distraction of standing or sitting. Overall, kissing horizontally can be a special and intimate way for couples to connect and show affection towards each other.
