Have you even been reading a really beautiful poem or section of prose and been totally enamored with how well the author is expressing their passion for their country/a bird/the ocean/a slice of pizza/probably the moon, only to have the poem turn and really be about how much they totally want to bone some beautiful human being? Maybe, like me, you audibly groan and put the book down, feeling cheated for the potential that an author is capable of loving something that is unlikely to give them a satisfying sexual experience.
If you haven't had this experience, you aren't reading enough, or this sort of thing doesn't bother you.
Try and find a piece of writing that stumbles over objectification (or somehow makes the act of objectification seem lovely) and let it inspire you to write about something you are passionate about. Express this without mentioning a person in any way.
