The smallest measurement defining the size of one's chest size; neither objectively better or worse than larger breasts. The derogatory term "
flat-chested" is considered synonymous to it. Often times disregarded as beneficial due to its disbenefits, despite the
plethora of advantageous properties it has. Typically not seen in an even light with larger breast sizes.
Long story short, smaller breasts can satisfy almost all needs larger ones can, and it works the same vice-versa. For example, smaller breasts can be played with and so can larger breasts. However, smaller breasts allow closer interactions while larger breasts get in the way. There are also, obviously, things smaller breasts cannot satisfy and larger breasts can. One of those things include a
titjob, a kind of foreplay that involves the use of one's cleavage (and the rest of
the chest's soft cushions) to jack someone off.
In any case, those with larger breasts suffer quite a lot on a physical level. Those with smaller breasts suffer quite a lot on an emotional level. Either way, both should be equal.
Please, be kind.
It isn't nice to weigh the scales unevenly.
Example:
Girl 1: "I may only have an A-Cup, but it makes life a lot easier. I don't have to worry about the back-pain or stairs. There won't be shirts I don't fit anymore, jackets I can't zip all the way or button-ups I can't button up. I don't have to buy tons of bras, and won't have trouble seeing over my
bussom. I just wonder what it would be like to have them bigger. I can't help myself. Mine are just so small! It makes me feel so inferior to look at other girls and see that they have bigger ones than I do."
Girl 2: "I understand, I'm not that much bigger than you. Mine are C-Cups. Sure, I'll look around and see girls with larger ones than mine, but at least I won't have nearly as much trouble. If I can take care of mine well, they won't sag much like people think. Of course, I still experience a lot of the issues you said you won't have to go through. You're lucky to have
small breasts. The only real benefit of larger breasts I can think of is to just make you feel sexy."
Girl 1: "I get you. I honestly don't know why it matter so much to me, either. I know
the pros and cons of smaller breasts. The thought of having bigger ones is just so compelling."
Girl 2: "I guess? Don't change yourself to make yourself more,
quote on quote, attractive. Lots of people think A-Cups are cute or sexy, anyway. If your chest
size matters on whether or not you get into a relationship, you probably shouldn't
get into it."
Girl 1: "Yeah, yeah.."
The conversation goes on and on.
