What does a girl feel when she sees a man who she finds physically attractive?

[Nicholass]

When a physically attractive man walks by her, for example, what goes through her mind? What parts of a man is she most fixated on? What does attraction feel like?

I only know what it feels like for a man to be physically attracted to a woman, and am curious about the differences and similarities.

she fixes often guy's ass, or shoulders.
