There are practical considerations to go with this interest: (1) the average bra size of an adult woman has dramatically increased from 34B to 34DD in the past 20 years or so; (2) more than 250,000 women per year receive breast augmentation procedures. Clearly, there is a significant trend going on.
So what do we know about men who prefer them large, as opposed to those who have more modest preferences? Lots of things:
(1) Hungry men prefer larger breasts, according to Malaysian researchers Swami and Tovée. This may relate to food supply insecurity. They are most strongly fixated on bigger hooters before meals, and less so later. (This could be exploited by television programming.)
(2) Sexist men prefer larger breasted women. This translates into traits as preferring traditional femininity, hostility towards women, and benevolent sexism. We can infer, therefore, that less well-endowed women might draw fewer jerks!
(3) Men who more strongly want to become fathers prefer larger breasts on women; men who are not as inclined prefer smaller breasts on their ladies.
(4) Financially more secure men tend to prefer smaller breasts on women, while those less secure tend to prefer them bigger. Is this a form of compensation?
Interestingly, a woman's breast size had no effect on the amount of time males' eyes tracked her chest. In other words: whether you're large or small, the eyes of Texas are upon (your boobs)!
Ladies, the fact that you have breasts that might be stared at by guys might confer certain health benefits to them. Therefore, you might consider yourself a gratis health care provider!
Here is another health care provider taking advantage of this technique of alternative medicine:
Finally, research on breast implant size chosen for augmentation surgery indicated that size chosen was affected by current breast volume, goals, body habits, and possible breast sagging. In the warmer states like Texas, Florida, and California, average implant size ranges from 300 cc. to 425 cc. In the Midwest and Northeast, breast implant size ranges from 250 cc. to 350 cc. In Europe and Asia, the average breast implant size ranges from 200 cc. to 300 cc.
In the United States, most women who choose breast augmentation surgery aspire to C-cup breasts.
