I'm in huge disagreement on society norms somehow putting a clamp on male's lust for busty woman. I think the questions not being asked are
what is big and what is too big. Society does in fact least aesthetically favor busty women, but it's important to remember that this is mainstream busty (C-DDD). These are woman like Christiana Hendricks, kim kardashian, coco austin. Look at the women in your videogames, animation, male oriented magazines, male oriented shows. It's perfectly normal to like big breasts, but remember big is a relative term.
I don't like the idea of trying to rationalize a fetish or kink "See! We're the normal ones! The rest of you are just repressed!", no, there are a billions reason why not to like big breasts, just as there's a billion reason to like big breasts. At the end of the day breasts are breasts, big breasts, small breasts, or average sized, they're breasts. Your preferences for a certain size can be dictated by a number of things (experience, environment, culture.......etc), so nobody's being repressed.
To answer the original question...It depends on the entire package or parts of the rest of the package. I've had overweight friends or not what people would call "pretty" friends with very large breasts that get no more attention than the average person. Women with obvious larger breasts that have an attractive face and reasonably fit body definitely lead a charmed life.
This is true. hate to break to people but most women with big breasts look nothing like Christiana hendricks or Merilyn Sakova. They're often times pretty heavy set women with big breasts but the breasts do nothing for their figure. Of course there are exceptions and those are the one's we generally lust over.
Again let me just reiterate attractiveness is no measurement for the quality of someone's life or a gauge for their happiness. It is naive and a little silly to think that a big breasted woman - her breast size being one aspect of her life - has a charming life, especially in this day and age, where the popular opinion is the opposite.
