Like, you can see a leaf on and think “wow, that’s a beautiful leaf”. You may even pick it up to admire it (especially if you’re a child or a biologist). You wouldn’t do that with a strand of human hair, a human nail clipping, or even less with the parts that aren’t supposed to come off like hands or eyes.
And if someone does fuck a person without feet, it’s gonna be assumed that’s the primary reason as opposed to any of the parts the footless (or… footloose? Sorry) person does have.
Humans are weird.
