Women and breast size is like men and penis size. There are certain truths.
[ul]* Within our same sex, size matters a whole lot. Power rankings or something. Bigger = higher on the totem pole.
* No matter what the opposite sex says, we will never really believe that it isn't as big a deal for them.
* We all see unusually large or even small one(s) and might wonder what it'd be like to take that for a test drive, but that doesn't mean we'd necessarily prefer it for our daily driver. Could be far from it.
* Most people prefer average-ish.
* Just like Rule 34 teaches us. If you can imagine a body type, there are a whole bunch of people out there who find that the most attractive person in the world.[/ul]
