Eye tracking studies show that it is women who spend the most time looking at women's breasts and cleavage, which I have seen described as "subconsciously comparing them to her own".
These days I find it difficult to look at a woman's breasts without assessing how breasts in her shape and proportions would look on me, and categorizing them according to what I would like for myself. "Too small. Too basketball. Hmmm, I like how those look on her, but... ah yes, my calculation is that those would project 6 inches on me, and that would make me look like a terrible breast fetishist and I sure would get stared at... Oh yes, those ones, those would look great on me, so now let's get measuring proportions so I know what size to tell the plastic surgeon..."
