I only want to go the route of BA as an absolute last resort but i wanted my breasts to be in the DD - DDD range without implants. I've seen quite a few MTF women with big breasts without implants. I was hoping — and am still hoping — to be one of them, partly because i love big natural boobs and also because if i had big breasts naturally i would feel more like a cis woman and feminine than trans.
I've been thinking a lot about getting a BA though. I still have the buds beneath my nipples. I've been HRT'ing since April 2014 and i believe i'm still in the A or B cup range.
Here's the thing though: I want my breasts to jiggle and bounce like Jell-O when i move, and I want to show cleavage and for my cleavage to look nice. The cleavage, i guess, but the jiggling softness i don't think is possible with BA. But i wanted that natural-like teardrop shape, having them drape a few inches down my chest i guess? That's the best way i can describe it.
The idea of me getting a BA feels off and depressive for me but again it's only as a last resort.
