With respect to your comment, sir...
People who don't have breasts should not talk! You don't know shit about it. You don't need to deal with things that constantly come in your way. You don't have 'sore boob' days. You don't need to deal with which bra to wear when, what kind of bra is appropriate. Hell, you can't even throw away the damn thing. Plus the social premium on big breasts. Why in hell's name would anyone want something so big that they can't look at their own feet while looking down.
Talking about it, sharing common issues, discomfort, etc is not a sign of insecurity. If anything it shows that someone is 'ballsy' enough to be able to bring it out in the open. A comment such as yours, esteemed sir, is a comment on mankind. Snubbing us about it won't help you escape. Try stuffing a sanitary pad up your crotch and mentally multiply it by 12 and 30 and you might get an idea of the pain a woman endures. We don't need to put up with objectification on top of that. I suggest you pull out whatever you have stuck up your backside and learn to talk to me rather than us.
