A/ Very rare these days and technology of implants has much improved, remember they started with silicon...
B/ Eh?
C/ You opinion only - if smaller breasts were popular would there not be much less demand for implants?
D/ Ok - most sensible people that get implants get the size that match their body type
E/ lol
F/ Look at this from a small breasted womens perspective, you expect them to go all thru their life with something they're not happy with, it's not like a diet where you can lose fat if you're not happy with your weight...
