Guys.. girls who develop early with big breasts go thru amazing amounts of SHIT! I was wearing a bra in 5th grade and was a size D in high school. I even had high school teachers tease me about them. (Cool as a website theme - not cool when you are 16 and sitting in class.) So it can be annoying depending on how guys phrase things.
I think women should be happy about their bodies and themselves, but as you can tell I'm not very modest! Although I am happy with my boobs and have always had plenty to say back to the more "eloquent" comments.
