I seriously doubt supply and demand had anything to do with the FDA's edict, they just like to assert power every chance they get, even over the most innocuous or beneficial things. While I do not know how many girls are wanting the OMG implants, I do know that they are choosing larger sizes than just a decade ago and more are choosing to go offshore to get it done. I read some time ago that over 50% of girls wish they had gone larger and that like 22% will return within 5 years just to go larger. While Brittany had to downsize twice for a medical problem, not that she wanted to, expanders offer that option also, but we would see far less regretting not insisting on a larger size to start.
And I don't know exactly what it is, but there must be quite an attraction a girl feels with each expansion, because once they start, they want to keep going, well past anything they imagined. Foxy & Beshine are prime examples; somewhere in that 2000cc to 3000cc range, something happened and they kept wanting bigger and bigger boobs, the urge just getting stronger with each expansion, the anticipation greater.
Yeah, 100cc may make a A cup a B cup, but when we are getting into the middle of the alphabet, it means nothing. Simple geometry; you need to increase the volume of any shape by 8x to double the exterior dimensions. So that 500cc D cup breast size needs to be 4000cc to double the size of the breast, just a little smaller than Brittany was before she had to drain.
And yeah, I still credit Beshine and her willingness to spend whatever it took to have permanent expanders made; her efforts gave birth to the expanders of today. Old expanders were a temporary, very thin walled implant used only for stretching the skin. Way, way thinner that a regular implant. I find it remarkable that today's implants can safely expand to 5x the intended size, though like that video of a 500cc implant filled to 50,000cc, I would be a bit wary of how long they would last after such a stretching.
Still, I have to believe that if all implants were expanders, not only would we have fewer girls regretting accepting a smaller size, but we would have a lot more girls getting fills even after they already had passed any initial goals. Ask Foxy, she says she had no idea that she would want to expand her boobs so huge, yet here she is, 10,000cc and wishing she could go even bigger. Something must feel so right.
