Yes they are hypersexualised and I think now more than ever before. Because long ago women in Western cultures were required to cover up, now the nipples, buttocks and genitals are the final frontier, hence the hypersexualisation.
I used to work with aboriginal people in Malaysia and in their culture, breasts aren’t sexualised, and women go about topless with no problems. However women are expected to cover their thighs, traditionally with grass or leaf skirts but later on with sarongs. So I guess women’s body parts get sexualised the world over, it’s the individual culture that determines the specifics.
