I believe we are hard wired to find breasts and buttocks sexually attractive /arousing so we will want to procreate and continue the species. The alpha males will seek out the best breeders and selecting a female with broad hips and breasts will provide the best chance of continuing his line. Well thats evolutionary significant anyway.
Modern man, i am not so sure. He seems terribly confused about his role, about women, and sex.
Young men are not confident about their once expected role of family head, provider, protector and procreator. And at the same time young women are being taught to be more independent on one hand and overtly sexual on the other.
Personally i have always been attracted to breasts. I was breast fed but, not for years like some boys.
I grew up fascinated by and wanting to see bare breasts without much success in that era (1960s.)
I don't think i have changed much 😁
