I think a lot of it is social conditioning. Would you look at it differently if it was pointed out that they are nothing more than bags of fat hanging off a woman’s chest?
However, having said that, human females are the only mammals to have evolved to have permanently enlarged mammary glands, as though we were breast feeding which = fertile. Think about it…cats and dogs only have enlarged mammary glands when they ARE nursing a litter.
As to why so many seem to think size matters? I have no answer to that. Social thing, I guess.
It’s all stupid to me. My views on breasts changed when I had my first baby, who I breast fed until she was 18 months. One time we were at a check out line and she spied a Cosmo magazine which, of course, featured breasts up and center.
My little daughter goes, “Numma numma, numma!” I had to laugh. Nursing is what breasts are for.
