I think I would agree with a combination of lost's and Honey's answers: Larger breasts will get you a lot of attention, much of it unwanted, but they are irrelevant with regard to behavior in a long-term committed relationship. And to take Honey's analogy a bit further, few would believe that a man's size correlates with his desire to have sex, so long as he does not get repeated negative feedback about it.
OG_Lou wrote that he's "attracted to what's inside." I wish I could claim to be so noble. I am attracted to my wife's gorgeous body, and to much of what she says and does, but NOT to her sexual behaviors. She goes out of her way to thwart my desire.
