It's actually pretty much a weird cultural thing. A lot of societies didn't and don't find breasts or big breasts erotic at all. I know a few African and indigenous South American ethnic groups think the West is entirely made up of ridiculous manbabies, because breasts are just for feeding kids there, and nobody sees them as a sexual thing.
So, bad evo-psych loses. lol
