Make sure your desire for larger breasts is not just to fit into any specific dress. Understand why you want bigger breasts of a specific size.
I have a B cup and sometimes wish for just a little more but certainly not a D or larger cup, regardless of band size. Back problems can occur with hefty breasts. I think that as more muscle seems to leave the chest area, the larger the breasts should appear too.
I see many women with apparently small breasts that are certainly feminine, and they look lovely, and women should not be defined solely by boob size. Although many people seem to pay attention to big boobs and many women want big boobs and even some moms are paying for cisfemales to get breast augmentation as the daughters start college!
If a woman wants breast augmentation that is certainly understandable (within reason, no need to set world records for size) but each of us need to understand why we want that.
As everyone is different in responding to HRT, orchies, body fat transfer, etc. I think that waiting to see what development one gets is a good idea. We all need to be patient. I may indeed try to see if I get a little more development with a higher E dose even though I have been on it for a long time now. But if I do not try, or I do not get larger there, so be it. I just do not see me getting a BA.
I do not know how long any specific female should wait before getting a BA. It is also such a personal decision for each to make. More of anything is not necessarily better except for love, kindness, caring, faithfulness to the Heavenly Father, patience, and other good beliefs and behaviors.
Keep on sharing your thoughts here.
