This thread is making me feel good about myself. No big boobs here and that always makes me feel kind self-conscious, but I'm built pretty light overall. Seeing guys drooling over girls whose frames somewhat resemble mine is a nice mini self-esteem bump.
You should never feel self conscious about having smaller breasts, EVER. I hate fake ones and I really hate it when a really nice looking lady goes to the plastic surgeon and comes home a stripper.
In my opinion women with smaller chests look much sexier in clothes. Something about big boobs just makes clothing not flow as well from my point of view. I have had women of all different breast sizes and the smaller ones are actually nicer since they don't have stretch marks and they tend to stay in place as you age. Gravity is a bitch.
Only little boys see a woman as a set of boobs or a booty and they can have them. A woman is a package and balance is preferable. I will take a slender woman with small breasts and a small backside any day and every day.
It must be that I am old because back in my day very few people were really fat like today and most women were not plus sized.
