ELI5: why are female tits so sexualised ?
gpt
They are a secondary sexual characteristic and as such indicate that the woman is past puberty and therefore physically developed and ready for producing offspring. Them being large indicates that she is well fed (not an issue in modernity) and them being firm indicates youth and health. These factors give some very base instinctual attraction to them in a sexual manner. Western society (particularly American) amplifies these natural impulses by focusing on them as a sexual region of the body and making both nudity and sexuality taboo in open society.
