Hmm...
There was a special on the Learning Channel many many years ago in a series that was called "The Human Animal" that dealt with sexuality. In that episode they presented evidence from studies that claimed that the roundness and fullness of a woman's breasts are an innatue visual cue which reminds the male on a subconscious level of the roundness of a woman's buttocks and pelvic curve that has a pelvis that is a bit curvy which in itself is another cue that represents a woman that may have an easier time with child birthing. It was sort of spooky when they showed a close-up of two women with low cut dresses and almost identical breasts only to reveal by panning out that one woman had a low cut dress in the front and you were viewing breast cleavage and the other woman had a low cut dress in the back and it was showing butt cheek cleavage.
They also stated innate cues also reside within women....that a "v" shape in a guy tends to show strength and someone that would have been a good provider in rougher days of human history (but too much muscle is an open cue of possible vanity and that was a turnoff for most women), and that the reason a woman lights a tight, hard ass on a guy is that it dennotes greater thrusting power.
Interesting show, but much of that could have been speculation.
For myself too big in the breasts in many cases goes along with too large of a butt as well, and I guess I just prefer more streamlined women....ones that look more built for speed than comfort
Perhaps for some guys the great attraction for very large breasts lies in the fact is that they don't want their girlfriends all sad or pissed off because their bra-suze would be bigger in cup size than that of their girlfriends ....MAN-TITS.....brrrrrr.....you should ask around how many gals find those things attractive.
