Heh, I would say that looking at a woman's "rack" breasts are one of the things that the male uses to ascertain weither or not he wants to sleep with her. I think it's more on a subliminal level meaning he is choosing the best mate to carry on his genes. If you recall, not that all women do this, but one of the main purposes of having them are for feeding an infant. I mean I could be full of it but doesn't size go along with fertility? Most men I would think look even without trying, or even knowing we are doing it. If she notices, well then all the better, because then you get the chance to make eye contact. I love it!
