99.99% of the time it's not objectification, it's effectively shouting "You have awesome physical characteristics, I'm attracted to that!"
what's the difference?
It's pointing out that they are attractive, validation of effort put in to their appearance. Objectification is treating somebody like they aren't actually human, like they're a commodity for trade or their thoughts don't matter.
It's painfully obvious so I don't get how you can't make a distinction.
