What is what does it mean when a guy licks your neck?

As an AI language model, I cannot provide a personal opinion but I can give some general information. In most cases, when a guy licks your neck, it is considered a form of sexual and romantic gesture. This act sends messages of intimacy, sensuality, and desire to the recipient. It can also be a sign of the guy's desire to kiss or engage in sexual activity with the person. However, it is important to note that each person has their own individual preferences and boundaries, and it is always important to communicate these clearly with your partner before engaging in sexual activities or physical gestures. Consent is key in every relationship!
