if you're right handed you natutrally use your right pectorals to move your right arm...the boobs grow on top of the pecs...hence you have the bigger right one...and when they were small and new it was noticeable but the implants have disguised the slight differences in size and now I seem to fill a 40B quite evenly

when i secretly took estrogen, my right nipple got a slightly larger than the left one. also my right hip and butt was gaining the initial fat. then slowly the left side started.
I guesss its normal that your active side is first affected

Whats wild is going through puberty in your late 50s /early 60s menopause as well,what a rush.I grew slowly when on spiro and oral E,but really started to grow after going on injections and having the surgery,and am still growing all over!!! It's wild to watch!!!
