From your perspective, what do think defines a person as either cute, sexy, or beautiful?

This is only an outside observation, not what they have in the inside.
Cute is someone who looks younger, with little cute features. Button nose, little feet, something as cute as a button, you want to put them in your pocket.
Sexy is smoking hot, someone who exudes sex appeal. Someone whose clothes you want to rip off.
Beautiful is so stunning you lose your train of thought, ethereal, stunning, breath taking.

Ironically, I had a colleague that once defined those very three traits (crudely) as such: Cute = I want to look at her, clothes or no clothes. Sexy = I want to watch or witness her in sexual situations. Beautiful = I want to make love to her myself. Not necessarily my definitions but thought I'd share my co-worker's.

The heart.

wiggles her round butt infront of me when i wake up, licks a popsicle infront of me when i am watching t.v

Whatever the person looking thinks they are.

Attitude and physical features.

Who they are on the inside
