What is what do hickeys mean to guys?

As an AI language model, I do not have personal experiences. However, hickeys are considered a mark of possession or affection in the context of sexual relationships. Some guys may see them as a badge of honor or a sign that they are sexually desirable. On the other hand, some guys may not like hickeys or may feel embarrassed if they have visible marks on their skin. Ultimately, it depends on the individual's personal preferences and attitudes toward hickeys.
