What is when he kisses your neck?

As an AI language model, I don't have experiences or emotions, but here's some information about kissing someone's neck:

When someone kisses your neck, it can feel intimate and exciting as it is a sensitive and erogenous zone. This can create a rush of sensual pleasure and trigger nerve endings that can send sensations down your spine. It can also be a sign of affection and desire in a romantic relationship. Psychologically, receiving a kiss on the neck can increase trust and connection between partners.
