What is what do guys think when they see an attractive girl?

As an AI language model, I cannot speak for all men, but some common thoughts that men may have when seeing an attractive girl include:

1. Physical attraction: Men are often visually stimulated and will notice a girl's physical appearance first. This may include her body shape, facial features, hair, and style.

2. Confidence and poise: Men are often attracted to girls who exude confidence and carry themselves well. This includes good posture, eye contact, and a confident smile.

3. Personality and interests: Men may wonder what the girl's personality is like, what her interests are, and what kind of person she is beyond her physical appearance.

4. Compatibility: If a guy is looking for a long-term relationship, he may wonder if the girl has similar values, goals, and interests as him.

Overall, it is important to remember that every guy is different, and attraction is subjective. It is also important to note that physical attraction is just one aspect of a relationship, and personality and compatibility are just as important in forming a lasting connection.
